WoW thank you so much! I would have never guessed in a million years to just cut/grind a bolt to a length I needed! Oh my what would this world do without geniuses like you..... eyes rolling
Dude and wtf was the point on grinding off your hardness rating on top of the bolt..? Also, you want your bolts to be softer and be the first piece to wear instead of whatever housing that bolt is threaded into... Wtf was this? Hopefully satire...
I have been working on just about everything from mini bikes to restaurant equipment for over 54 years and am still learning. Learned this the hard way years back & I am always looking for ways to get er done. So your title “OLD MECHANIC TAUGHT ME THIS YEARS AGO! “ caught my attention. Years back I only had a hack saw to cut with & this method was necessary . This is a good tip for newbie’s and others that may not turn a wrench too often and others that did not figure it out yet. I do not understand all the negative comments. If the experts have a problem with this why did they even click onto the video or better yet just produce a video series on whatever they do as experts? Well that’s my $.04 worth. Stay well Joe Z.
Nich Farnham Welding a matching rod to the end of the bolt and tapping it can lead to satisfactory results, if every step is being made in the right order.
I just want to say something to those with the negative comments. Not everybody that watches TH-cam have had the privilege of learning certain skills, such as the bolt modification in this video. Lighten up and let live. Everybody is at a different place in their learning and understanding. I hope there are 12 year olds watching this great video, instead of other worthless options. I learned this from my dad when I was about 13 and it brought back great memories! Great video!! Jeremy,from Michigan
Jeremy Warmuskerken exactly. I've been a maintenance technician for 20 yrs and always looking for new tricks even though this may not be new it's new to someone
So true, we aren’t all blessed with elders who’ve shared their experiences and knowledge. I was lucky to have three practical teachers (2 x Grandads and a Dad) who all had a wealth of knowledge on tricks like this and a desire to help me learn, some stuff they let me learn from experience, some stuff they taught me. I’m forever grateful for their support and guidance. Why wouldn’t we encourage our children to learn some tricks here and then help them with the hands on stuff? My seven year old daughter is a hands on type and I hope she will be cutting, grinding and welding before she reaches high school 😀
Kent Brauer. It wasn't explained anywhere in the video. Then I would have painted it. Because if I'm doing a restoration I would protect the fasteners from corrosion. Just saying.
Simple - but a good little video that novices may learn from. How many guys will cut a bolt or threaded rod without using a nut to chase it and then fight and file to get a nut to go on. All the experts can laugh but it happens for sure. Why grind off the coating and markings? To make it look correct when trying to restore to original. This is a very easy video to make fun of - I almost did myself -but while a no-brainer for experienced guys, a lot can use these tips. How many guys would cut the bolt, install and paint - only to have people critisize or at a judged show lose points because of having the modern bolt heads showing? Not rocket science but a good video!
I did the same thing and no mechanic taught me, mainly common sense for me.. using a grade 8 bolt in place of a grade 2.. I dont know if I would have done that.. for reason's.. the bolt is designed to be drilled out encase of snapping off the head, corrosion, being stripped or the end of the bolt gets mushroomed from over tightening.. using grade 8 makes it harder to remove... as a rule of engineering design grade 2 to 5 bolts use for bolting in legs or supports they serve no function other than holding something in place and dont need grades beyond that.. no purpose to grind off the grade 8 markings and sides that are plated? but like assholes everyone has an opinion, including myself..
I was going to hammer you about the removal of material from the sides of the bolt head until I saw your clarification video. Now I can see that you only removed the plating so that paint will adhere. This "Old Mechanic" appreciates the fact that there's young and honest people out there that are restoring and conserving our past. That are also willing to share what they've learned with others using newer technology such as TH-cam. When I was young there weren't many people who cared about the past. This resulted in the disposal or destruction of so much without regard for the fact that what they're disposing of will be lost forever and that it may have future value.
been wrenching and running maintenance programs for 40 years. Millwright, car mechanic, truck and coach, and factory trained Harley mechanic. I usually am more interested in seeing how someone else does it so I might learn something than criticizing. But hey,, I am not an expert.
Funny...sometimes the best solution is right under our nose. That's why old mechanics are great - they know so much incredible, time-honored, wisdom..thanks, guy. :-)) (wife of a retired marine guy)
I used to get sent out to do repairs in the field. My no-no word to the staff was "easy", they were never to refer to a repair job as "easy". It was uncanny the way "easy" jobs turned into 3 headed monsters.
Dan 255 Tl;dr: This is only a no-brainer to me and to you and a number of other people, but it isn't to others. (Comment written before I added the tl;dr, first sentence might be especially awkward unless read as though it was first sentence in comment.) But this isn't accurate. I remember when I was growing and this was exactly the kind of simple trick that would blow my mind. And I was one of the kids with a clearer head most of the time. If your talking about anyone else who would have made me look like I had it together (note: I didn't), then all of the sudden this video becomes crucial to exist, we can talk all day about the complex stuff but as far as I've observed, people struggle getting into various fields and such because there isn't enough showcasing of the basics because it's assumed as "common knowledge." Well, common sense isn't common, and we thus have a knowledge and competence gap between groups of people, not necessarily because of economics (though I'm not discounting problems there affecting everything), but purely because of a cultural phenomenon. (when taken on its own merit outside of economics.). So I'm of the mind that I'm not going to take anyone's knowledge base for granted, I will not assume they should know something so much. (Hmmm, I might have to come up with an example or memory of what I've observed if you press that detail, which would be fine of you to do. I didn't really back that up well here, but comment is long enough already.)
My pa taught me this trick when I was about 10 yrs old. Some people don’t have fathers or anyone to teach them things. Nothing wrong with passing on this knowledge.
You know utube is a tough crowd, good job dude! I have done the same thing many times. I never throw away any extra bolts or screws just for that same purpose.
The "trick" he is advertising here is to put a nut on before you cut it, so removing the nut AFTER the cut will fix the threads. You obviously have never cut a bolt and then tried to screw it in without fixing the threads (messed up from the cut). So you tried to be a smart-alec on a video WAYYYY above your skill level...how did that work out?
I've cut off thousands of bolts in my life, putting the nut on is..... "nice" but I NEVER do it. and never have an issue with them threading up either, on a rare occasion, a slight file to the edge.... but not often. Gary Cooper above.... I had to laugh when I saw this as well. BUT... there are plenty of people who probably could learn from this and never would think of "cutting off" a bolt in stock. But then again, they probably trip while they are chewing gum and walking too.
The replacement bolt shown is a Grade 8 bolt, indicated by the 6 radial lines on the hex head. A Grade 5 bolt, not shown, will have 3 radial lines on it. A plain steel bolt with a zinc finish will have 0 lines. Grade 5 bolts are 30% stronger than plain bolts in terms of both tensile (load along the axis) and shear (across the axis) strength; they are also more resistant to rust. Grade 8 bolts are even better as they are 60% stronger than plain steel. I commend the TH-cam contributor's bolt choice as this is a worthy upgrade to a failing bolt. While I understand the double-nut trick in the bench vise and the shortening with a grinder, I do not understand why the 6 lines were ground off the head (as was noted in other comments). Why not communicate to the next mechanic that a Grade 8 replacement is a good idea? *** Different topic - the passing of maintenance knowledge to others. It is simply not true that "everybody knows that". That's like saying a pro football coach can drive across town and manage the baseball franchise and that your dentist can give you an eye exam. TH-cam is a DIY sea change. I've used it to (a) cut down a dead tree; (b) repair a stopper on a pedestal sink; and (c) replace the display on a laptop. In each case I watched at least 3 different videos and learned something from each one not covered in the others. Then I had a plan for tools, parts, and manual help. I was able to complete the projects on the first try; in the case of the tree, safely. So experts, please keep loading videos like this one in your area of knowledge. You probably won't be around to help your great-grandchildren but your video will be available forever.
Penny Lyons he never said he just learned it. I think he's probably been doing this for years, and just saw the opportunity to share it with ppl that might not have known what to do. That's a lot of what he does... good grief!
This helped someone, somewhere. Sometimes you came really far, and can't remember the learning process. Not only that, but it was a good metered approach.... I watched the whole time waiting for the old timer trick. :) Thanks for making videos
Awesome trick, I used to use a hacksaw to shorten a bolt and then had to file the burrs down. Your way-faster smoother & easier! Especially having the two nuts on high side to make sure you can spin them off. Ignore the haters. Gotta love it!
When I have a son I will teach him this he'll ask 'where did you learn this dad' Im gonna tell him 'from a man in an old video who learned it from an old mechanic' and thus moves on
Just adding this to clarify my earlier comment. This is the method I use when cutting or grinding a bolt shorter. I just mentioned the thread file as a "BTW" comment. Great video. Great channel. You "Best Bacon" video is still my favorite YT video of all time.
True, but sometimes a dinged up first thread can be tricky to get a die started on properly (in other circumstances, not cutting like this). A file is pretty handy then. The more tools the better.
I taught this trick to a neighbor who was a pro mechanic back in 1968 when I was 16 years old. I still use it today with one added step to what you showed. I use a powered wire brush to clean the end threads up after removing the nut. I also have run into situations where a bolt is available, but the wrench size does not match the other bolts in the assembly. You can use a bench grinder or an angle grinder to "shave" down each facet of the head to match the correct wrench size, then chamfer the top edges to make it a bit smoother and to match the existing bolts' shape.
That video doesn't answer his question. Why not just cut it off close to the nut, then grind down a little tiny bit more? Seems that would be faster than just simply grinding down an inch or whatever off a bolt.
I figured he just didn't feel like answering the question and cut and paste a link instead. Not a big deal. I've cut hundreds of bolts to length flush with pre-attached nuts with zero issues. And it's a lot faster than grinding the face. I really can't think of a single reason why one would grind a bolt to length unless the length being removed is, perhaps, less than the diameter of the face. And even then cutting is likely faster. Preference I suppose.
Power tools? Grinders? hah. Wish I had that stuff growing up in the 70s trying to work on our cars. I had screw drivers with chipped ends that had wooden handles, dull almost useless files. We had one socket set with mixed pieces from various brands literally shared by all my friends.
I've seen some people's inherited tool sets, what the new owner see's as treasured heirlooms, I usually see as mix matched, low quality imported junk from the 60's-70's.I would never ridicule this, but I feel bad when they think they now have something to work with, only to see a project fail because in most cases, shitty tools create shitty work.
@ gk100... myself, as well, except it was ten years earlier, and only me. But, my Mom was an artist, and she had a school quality pencil sharpener in the house. I grew to really appreciate that sharpener for all things I did. Never had to use those cheap little suckers, or a knife. That sharpener is in my shop, today, still going strong nearly 60 years later. One thing about growing up poor, and with a limited number of tools; it has given me a much better appreciation for what I now have. I take good care of my tools, and I still have the first tools I started with. OVer my life, I have seen many guys sell there tools. I have been in some tight financial situations over my life, but I have refused to sell my tools. Why? Because I can always make money, if I have the tools.
@Pleasant Lake Pirate Arrrggg!!! I couldn't disagree more. With some exceptions, tools worn out, and non-functional, or ones needing to sharp, and can't be sharpened, tools are tools... The quality of work is dependent on the craftsman. Ease of completion, time of completion, long term effect on your hands/wrists, etc, tools can have a big impact. It's why I have a bunch of Snap-On stuff; I spent every day, for many years, using them every day. Jobs went faster, which meant I made more in flat rate, so they paid for themselves. Many of them are more comfortable in your hands, so you hurt less at the nd of the day. Others did less long term damage, so I'm no as bad off at 65 as some guys I know. I still us cheap ass tools, even though I have a box of Snap-Ons. I sure don't want to leave a 30.00 screwdriver, or a 120.00 ratchet at the wrecking yards, or use them in the mud, under my house. Tools have their purpose, different tools have different purposes, but the quality of the end product is more determined by the amount of knowledge, adequate planning and precise execution.
Snap-On is over rated and very over priced. And their warranty is useless if you don't live where there is a good distributer. I've got a 120.00 ratchet that I haven't been able to use for atleast 4 years now. Distributer doesn't want to do his job. Acts like if you're not giving him money he shouldn't give you service or something. I know I don't believe he's still waiting on a back order. Guess he's too stupid to realize taking care of warranties is part of his job. Then there's my 65.00 test light. Nice one. But the cord was dry rotten and the insulation started falling off about 2 months after I purchased it. And the only place you can get bulbs is from the fat lazy fuck who won't warranty any of your over priced broken tools. Then you got Craftsman..... Everyone thinks they are great. They suck. Sockets wear out extremely fast if they don't break first. And as for their warranty. They keep getting more and more that have none. And if you take in a broken socket you better not be wearing your work uniform. They won't warranty it. Then you have their practice of changing their suppliers. They start getting something from somewhere else and what you have is now obsolete. Can't get replaced or even parts for it . You're screwed
Yes! When cutting or grinding down a bolt you should always put a nut on all the way down. That way after you cut and/or grind it and remove the nut, the nut will correct the threads. (You probably should of explained that in the video.)
this is an important video, anyone that says its a waste of time is wrong.. We've all met the ' i dont have time for stupid questions' types. I'm usually pulling them out of a ditch or welding something for them at 2 am. im gonna do a video on using a hacksaw blade to hold the fuel pump rod in place or reversing a rear drum, put 3 lug nuts on it and use it as a battering ram to remove the axle, or how about, the screwdriver thru the impossible stuck oil filter...haha.
joe ferguson there's a lot of little tricks to make life easier wrenching
6 ปีที่แล้ว
and the filter just tears open with the old screwdriver trick then youre left with a stub to try and remove use a strap wrench and be done as for fuel pumps chevys got a bolt to hold the shaft ive never had to use nothing but grease to hold it on any others and if an axle wont come out i have a beautiful slide hammer that does the job fine
Lots of good mechanics/machinists buy HF tools for one-off or jobs they expect to do very infrequently. That saves them money so they can buy higher quality tools for jobs they expect to do repeatedly. There's no need to have a shelf full of expensive name brand tools you've used only once or twice now is there?
Buying a 50$ screwdriver doesn't make you a better technician, just like a 200K car doesn't make you a racing driver. You buy it because you can and like to show off. #getreal
I think this was awesome and tips and tricks are ALWAYS appreciated...IGNORE the critics...they usually think they know it all and they actually are the sloppiest
I worked in a machine shop for a number of years after I got out of high school, I remember some old Korean war vet showing me this trick. At the time I thought how silly, Why not just go to the store and buy some. Now that I have gotten older I see how this little bit of work and tricks like this can save you a lot of time.
As a 20-year machinist I was one of the ones that believed this video was common sense. After watching your "Exposed" video, I understand where you were coming from. Everyone's not journeyman machinist or mechanics. Nice videos.
Congrats. You made a grade 8 bolt look just like a grade 3 bolt. Didn't know that was possible. Seriously though chasing the cut threads with a nut already on the bolt does work great.
My dad taught me this one too. Learned it being raised on a wyoming ranch. Works even better if you also have a file and a thread file to clean it up real nice
Hacksaws always worked for me unless the bolt was harder than the saw blade. :) Then I use a grinder or file to bevel the last thread or two to 45 degrees just like they did when they made the bolt.
Smart! In Gunsmithing, when we don’t have a particular specialized screw, we make one to specs. Your vid is a reinforcement! Good for you! Keep doing great work! Semper Fi
boy am I glad an old mechanic taught you that, because if this is something you make a youtube video out of I'm pretty sure you definitely wouldn't have figured that shit out on your own.
I never thought of using a grinder. Hacksaws work but screw up the threads and leave a sharp edge that you have to file. I'll have to give this one a try.
Iam in total shock that u actually made a video! about that.....i thought for a moment that this was some sort of joke or prank!!! BUT u are SERIOUS!!!!......DUDE THAT'S JUST NORMALL EVERYDAY SHIT!!!, I cant count the amount of times ive done this in my 45 years of working!
It works without using the nuts as well, but yes, placing those two nuts ensure you will never screw up the threads plus you get it done quicker, otherwise it might not work from the first attempt. Good to know. Thanks for sharing.
Chasing the threads! I have a great hack for you! Dab a small amount of valve grinding compound on your screw tips especially Phillips heads! You keep the screws nice and you don't bugger up your drivers! I even add a small amount on my stones for sharpening certain knives and tools like chisels! Really, you won't believe it!
my go to--is vice grips and the bench grinder--then the air cut off. but we get to the same place. Snickering --great minds. I'm a tad OCD--have even finished em off with a hand file
What “pads” or wheels did you use for the cut off, polishing the marks off and the flats. Looks like there were at least three different ones. Red, green, yellow etc.
+John Icenhower They are from norton.the product line is blaze. Their rollock scotch bright is the best I have used. th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
I figured this trick out for myself about 10 years ago! Having the nuts on there automatically straightens out the last few threads and lifts the thinnest threads that need to be filled down so they don't hang up and block the threads when you go to thread it in it's intended hole!
I've been doing that for 50 years my grandpa showed me. Those old guys never threw anything away till it was used right down to the nub. Great tip for those who don't know. One comment, I am not certain what that blot holds on, but I doubt they made it a weak bolt just to be cheap. I'd say that cast part ain't cheap, so if it's a choice between stripping the threads in the part, or breaking and removing a bolt, I'd prefer breaking the bolt. That Grade 8 you put in there will tear the threats out of that cast part long before it breaks should someone over tighten it. Just a thought.
I remember when me and this guy were changing the starter motor on my car (conveniently placed under the intake manifold), and he said to me "If you can't find something that fits, make something that fits."
This is a good idea and will work good if you use the same grade Bolt the problem with a harder grade Bolt is somebody will over tighten the bolt in that casting and will strip out the threads in the casting then you really have problems. If you strip out the threads on a bolt you just replace the bolt.
+Walter Glenn Greer We got that covered. It will be in the build video. Thanks for watching Walter! This might interest You! th-cam.com/video/hmy96VUTxZo/w-d-xo.html
Great video. ¿What grinding wheel did you use to reduce the bolt length, kindly? (¿A flap 36 grit disk, as for a hand angle grinder?). Just wondering. Thank you.
Thanks for taking the time to post this. I’ve always shortened bolts with a hacksaw and then cleaned the end threads up with a triangular and flat file. The nut and abrasive disc worked well, real clean. I’ll try this next time,Cheers 🍻
Good video man! I hate seeing all the negative comments...you could pass out bags of cash and some would still complain how ugly and heavy the bags are! lol! People need to realize that this is an educational video for someone who is a beginner or simply looking for different ways to do things. Keep up the good work and don't let haters get you down!
What possible reason was there for grinding the grade markings off the head of the bolt? Also a cutoff wheel on your die grinder is much faster and easier.
Why grind the top and flats on the hex head? Trying to match the other rusted hex heads maybe? FWIW you can bevel the end by holding it at about 45 deg pointing down on a stand grinder wheel. Just a few light touches while turning the screw. This makes for easier starting in tight places.
I will try to remember this, I usually thread on a die and then cut, but sometimes you dont have the right tap/die. I find it almost impossible to get the threads aligned exactly when trying to cut the threads so this works except for a very, very short bolt lol.
I'm curious. Why, since you have 2 nuts to take off, didn't you just use a SLOW cut from a saw?I how it is a hard Bolt, but that was a lot of grinding. When done, 'twirl' the cut edge on a 45 degree lightly and the net will screw off and on by hand.
So how are you going to fix the buggered up mounting threads when your grade 8 bolt destroys them? A Grade 2 bolt was used for a reason and grinding off the Grade 8 marking won't make it a Grade 2 bolt.
I must be dumb , but I don't get it . I get the bit on shortening the bolt , but why go the trouble of changing the head of the bolt , if the threaded section fits through the hole , what is the problem ? is it because you want both to look the same from the outside. ? and I like the green vice. cool colour .
I'm sure there are loads of kids out there that this video helped to learn something new because they lack experience and as the Chinese say "one picture is worth a thousand words". The only problem is that now a days to many of them never get past the stage of looking at pictures and using their heads. So don't hesitate to keep up the Show and Tell.
you can take a piece of all thread or even the threads of a long shoulder bolt,cut to length.take a nut and thread it on but when nut is put on,use a high strength thread locking liquid or a press fit.let the nut be the bolt cap,let the locking agent dry,thread it into the item you want to secure.regardless it will become a jamb nut scenario whether the nut jambs against item or another nut is used on the other end.
I figured this out when I was in highschool on a sunday when everything was closed. Except I cut the bolt instead of grinding it down. Why grind the markings off the top tho? Nice how to.
What a fantastic trick to teach the younger generation of DIY's. I would stress that some form of corrision prevention needs to be added to the bolt head and threads before installation. Thank you for sharing and great job.
I learned this trick using my imagination when some one gave me bolts that were too long, The first time I did it I cut one the threads did not work. So then I tapered and deburred the cut and the bolt went right in and worked. As for the top part of the bolt I would just leave it alone most of the time
Thanks for posting. Don't mean to sound negative, but wouldn't it have been a lot quicker to give the old bolt a wire brushing and clean up the threads with a die (if you had one) than spend all that time mucking about finding and shortening another one?
even older mechanic taught me a trick many decades ago. you just melt steal and pour into a cast shaped like a bolt. its a pretty dope trick. just passing it on.
WoW thank you so much! I would have never guessed in a million years to just cut/grind a bolt to a length I needed! Oh my what would this world do without geniuses like you..... eyes rolling

Welding a matching rod to the end of the bolt and tapping it can lead to satisfactory results, if every step is being made in the right order.
That was funny..

Great video. I used to do this also. But, I used a hack saw. As long as you taper the end of the bolt the nut will go on.

I was going to hammer you about the removal of material from the sides of the bolt head until I saw your clarification video. Now I can see that you only removed the plating so that paint will adhere. This "Old Mechanic" appreciates the fact that there's young and honest people out there that are restoring and conserving our past. That are also willing to share what they've learned with others using newer technology such as TH-cam.
When I was young there weren't many people who cared about the past. This resulted in the disposal or destruction of so much without regard for the fact that what they're disposing of will be lost forever and that it may have future value.
+William Charles Thanks William!
I never knew there were that many experts out there.
+shovelhead8 Ha! Sad thing is there isnt.
Opinions and arses, everybody has one
been wrenching and running maintenance programs for 40 years. Millwright, car mechanic, truck and coach, and factory trained Harley mechanic. I usually am more interested in seeing how someone else does it so I might learn something than criticizing. But hey,, I am not an expert.
How did you ever learn anything?
I see why many channels are now blocking comments...not worth the aggravation.
Thanks for sharing this. I have been cutting bolts with a hack saw and then they were hard to thread in This trick grinding them looks a lot better
Funny...sometimes the best solution is right under our nose. That's why old mechanics are great - they know so much incredible, time-honored, wisdom..thanks, guy. :-)) (wife of a retired marine guy)
"Ah, this thing is going to run today" phrase that always screws up my projects
Yep. Jinx it every time.
+Zach G Ha!
I used to get sent out to do repairs in the field. My no-no word to the staff was "easy", they were never to refer to a repair job as "easy". It was uncanny the way "easy" jobs turned into 3 headed monsters.
Agreed ... Murphy’s law... and by actually speaking it aloud almost guarantees a whack with the ol shillelagh......
I appreciate the video and all but this was like a no brainer, every-one knows this.

Tl;dr: This is only a no-brainer to me and to you and a number of other people, but it isn't to others.
(Comment written before I added the tl;dr, first sentence might be especially awkward unless read as though it was first sentence in comment.)
But this isn't accurate.
I remember when I was growing and this was exactly the kind of simple trick that would blow my mind.
And I was one of the kids with a clearer head most of the time.
If your talking about anyone else who would have made me look like I had it together (note: I didn't), then all of the sudden this video becomes crucial to exist, we can talk all day about the complex stuff but as far as I've observed, people struggle getting into various fields and such because there isn't enough showcasing of the basics because it's assumed as "common knowledge."
Well, common sense isn't common, and we thus have a knowledge and competence gap between groups of people, not necessarily because of economics (though I'm not discounting problems there affecting everything), but purely because of a cultural phenomenon. (when taken on its own merit outside of economics.).
So I'm of the mind that I'm not going to take anyone's knowledge base for granted, I will not assume they should know something so much.
(Hmmm, I might have to come up with an example or memory of what I've observed if you press that detail, which would be fine of you to do. I didn't really back that up well here, but comment is long enough already.)
My pa taught me this trick when I was about 10 yrs old. Some people don’t have fathers or anyone to teach them things. Nothing wrong with passing on this knowledge.
Lol, there are people out there who can't thread a needle let alone cut a bolt down to size.
lol you know everyone? all 7 billion? wow.
Don't forget your safety glasses when grinding you bolt down to your nuts.
+Allen McKinney Ha!
You may need to wear a cup too.
You know utube is a tough crowd, good job dude! I have done the same thing many times. I never throw away any extra bolts or screws just for that same purpose.
I was shown this years ago. So simple and effective. Once you cross thread something the jobs knackered! Thanks for helping others out mate.
So ... if something is too long, you can cut it shorter? Believe it or not, I already knew that.
The "trick" he is advertising here is to put a nut on before you cut it, so removing the nut AFTER the cut will fix the threads. You obviously have never cut a bolt and then tried to screw it in without fixing the threads (messed up from the cut). So you tried to be a smart-alec on a video WAYYYY above your skill level...how did that work out?
I've cut off thousands of bolts in my life, putting the nut on is..... "nice" but I NEVER do it. and never have an issue with them threading up either, on a rare occasion, a slight file to the edge.... but not often. Gary Cooper above.... I had to laugh when I saw this as well. BUT... there are plenty of people who probably could learn from this and never would think of "cutting off" a bolt in stock. But then again, they probably trip while they are chewing gum and walking too.
+Brent Barnhart Check out another video on this channel.I recomend the line shaft grinder restoration. Leave a comment. Thanks
I use this technique when cutting all thread.
trev just hit it on the knotted wire wheel done !!
The replacement bolt shown is a Grade 8 bolt, indicated by the 6 radial lines on the hex head. A Grade 5 bolt, not shown, will have 3 radial lines on it. A plain steel bolt with a zinc finish will have 0 lines.
Grade 5 bolts are 30% stronger than plain bolts in terms of both tensile (load along the axis) and shear (across the axis) strength; they are also more resistant to rust. Grade 8 bolts are even better as they are 60% stronger than plain steel. I commend the TH-cam contributor's bolt choice as this is a worthy upgrade to a failing bolt.
While I understand the double-nut trick in the bench vise and the shortening with a grinder, I do not understand why the 6 lines were ground off the head (as was noted in other comments). Why not communicate to the next mechanic that a Grade 8 replacement is a good idea?
***
Different topic - the passing of maintenance knowledge to others. It is simply not true that "everybody knows that". That's like saying a pro football coach can drive across town and manage the baseball franchise and that your dentist can give you an eye exam.
TH-cam is a DIY sea change. I've used it to (a) cut down a dead tree; (b) repair a stopper on a pedestal sink; and (c) replace the display on a laptop. In each case I watched at least 3 different videos and learned something from each one not covered in the others. Then I had a plan for tools, parts, and manual help. I was able to complete the projects on the first try; in the case of the tree, safely. So experts, please keep loading videos like this one in your area of knowledge. You probably won't be around to help your great-grandchildren but your video will be available forever.
Michael, Thanks for the info on Grade 5 Bolts.
Good grief! I'm shocked that you've only just learned this 'hack'. I've used it for years!
Penny Lyons he never said he just learned it. I think he's probably been doing this for years, and just saw the opportunity to share it with ppl that might not have known what to do. That's a lot of what he does... good grief!
This helped someone, somewhere. Sometimes you came really far, and can't remember the learning process. Not only that, but it was a good metered approach.... I watched the whole time waiting for the old timer trick. :) Thanks for making videos
Some people needed to learn and see this...if someone is commenting about a easy job youve done,they didnt need to watch thenn.
Good job sir
Back when I was vo-tech in the late 1999. My teacher showed me this! To this day I do the same thing when I I need this done!!!
+soaringtractor th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
Awesome trick, I used to use a hacksaw to shorten a bolt and then had to file the burrs down. Your way-faster smoother & easier! Especially having the two nuts on high side to make sure you can spin them off.
Ignore the haters.
Gotta love it!
When I have a son I will teach him this he'll ask 'where did you learn this dad' Im gonna tell him 'from a man in an old video who learned it from an old mechanic' and thus moves on
+Josue Yanez Nice.
even better! when I have a son I would teach him not to learn from people that claims to learn this crap from an old fool.
+Janet Smith th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
You learned that bolts can be cut from a video? What?
Just adding this to clarify my earlier comment. This is the method I use when cutting or grinding a bolt shorter. I just mentioned the thread file as a "BTW" comment.
Great video. Great channel. You "Best Bacon" video is still my favorite YT video of all time.
Wow thanks. I would have never thought of that.
I am only 12 and I love videos like this. You made my day.
Good info. This may be a "no brainer" to some, but even they had to learn about it at some point.
BTW, a thread file is a handy thing to have around.
True, but sometimes a dinged up first thread can be tricky to get a die started on properly (in other circumstances, not cutting like this). A file is pretty handy then. The more tools the better.
+soaringtractor th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
I have used a thread file many times. No tool box is complete without one
+Gary Cunningham
Is that the little triangle one?
I like it. The fine art of deception. For a good reason. :)
Good info for greenies.If you think that's a hack you should see some o the shit we pulled off in the boiler room of an aircraft carrier!😅😅😅
I have heard from a retired Master Chief about it.

My Dad Showed Me That Trick About 45 Years Ago!Still With Me Today Thanks Dad.
I taught this trick to a neighbor who was a pro mechanic back in 1968 when I was 16 years old. I still use it today with one added step to what you showed. I use a powered wire brush to clean the end threads up after removing the nut.
I also have run into situations where a bolt is available, but the wrench size does not match the other bolts in the assembly. You can use a bench grinder or an angle grinder to "shave" down each facet of the head to match the correct wrench size, then chamfer the top edges to make it a bit smoother and to match the existing bolts' shape.
Why grind it down versus cut it to length while in the vise? It seems like the time would have been the same or less.
+Data Mobility Group LLC sure.
th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
That video doesn't answer his question. Why not just cut it off close to the nut, then grind down a little tiny bit more? Seems that would be faster than just simply grinding down an inch or whatever off a bolt.
I figured he just didn't feel like answering the question and cut and paste a link instead. Not a big deal.
I've cut hundreds of bolts to length flush with pre-attached nuts with zero issues. And it's a lot faster than grinding the face. I really can't think of a single reason why one would grind a bolt to length unless the length being removed is, perhaps, less than the diameter of the face. And even then cutting is likely faster.
Preference I suppose.
I use a hack saw and a file, same results. Then again, I'm not usually shortening Grade 8 bolts.
+Thomas Thedoubter Those grade eight are tough. Thanks for watching!
th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
This is done all the time on industrial maintenance
Power tools? Grinders? hah. Wish I had that stuff growing up in the 70s trying to work on our cars. I had screw drivers with chipped ends that had wooden handles, dull almost useless files. We had one socket set with mixed pieces from various brands literally shared by all my friends.
I've seen some people's inherited tool sets, what the new owner see's as treasured heirlooms, I usually see as mix matched, low quality imported junk from the 60's-70's.I would never ridicule this, but I feel bad when they think they now have something to work with, only to see a project fail because in most cases, shitty tools create shitty work.
@ gk100...
myself, as well, except it was ten years earlier, and only me. But, my Mom was an artist, and she had a school quality pencil sharpener in the house. I grew to really appreciate that sharpener for all things I did. Never had to use those cheap little suckers, or a knife.
That sharpener is in my shop, today, still going strong nearly 60 years later.
One thing about growing up poor, and with a limited number of tools; it has given me a much better appreciation for what I now have. I take good care of my tools, and I still have the first tools I started with.
OVer my life, I have seen many guys sell there tools. I have been in some tight financial situations over my life, but I have refused to sell my tools. Why? Because I can always make money, if I have the tools.
@Pleasant Lake Pirate
Arrrggg!!! I couldn't disagree more. With some exceptions, tools worn out, and non-functional, or ones needing to sharp, and can't be sharpened, tools are tools... The quality of work is dependent on the craftsman.
Ease of completion, time of completion, long term effect on your hands/wrists, etc, tools can have a big impact.
It's why I have a bunch of Snap-On stuff; I spent every day, for many years, using them every day.
Jobs went faster, which meant I made more in flat rate, so they paid for themselves. Many of them are more comfortable in your hands, so you hurt less at the nd of the day. Others did less long term damage, so I'm no as bad off at 65 as some guys I know.
I still us cheap ass tools, even though I have a box of Snap-Ons. I sure don't want to leave a 30.00 screwdriver, or a 120.00 ratchet at the wrecking yards, or use them in the mud, under my house.
Tools have their purpose, different tools have different purposes, but the quality of the end product is more determined by the amount of knowledge, adequate planning and precise execution.
Snap-On is over rated and very over priced. And their warranty is useless if you don't live where there is a good distributer. I've got a 120.00 ratchet that I haven't been able to use for atleast 4 years now. Distributer doesn't want to do his job. Acts like if you're not giving him money he shouldn't give you service or something. I know I don't believe he's still waiting on a back order. Guess he's too stupid to realize taking care of warranties is part of his job. Then there's my 65.00 test light. Nice one. But the cord was dry rotten and the insulation started falling off about 2 months after I purchased it. And the only place you can get bulbs is from the fat lazy fuck who won't warranty any of your over priced broken tools.
Then you got Craftsman..... Everyone thinks they are great. They suck. Sockets wear out extremely fast if they don't break first. And as for their warranty. They keep getting more and more that have none. And if you take in a broken socket you better not be wearing your work uniform. They won't warranty it. Then you have their practice of changing their suppliers. They start getting something from somewhere else and what you have is now obsolete. Can't get replaced or even parts for it . You're screwed
Pleasant Lake Pirate Sounds like a poor excuse for bad craftsmanship.
Seriously, I didn't think anyone over the age of 10 needed this advice. With respect, it's a no-brainer, good ol' common sense.
Yes! When cutting or grinding down a bolt you should always put a nut on all the way down. That way after you cut and/or grind it and remove the nut, the nut will correct the threads. (You probably should of explained that in the video.)
Yea that bolt didn’t need that cad plating anyway.....
roslyn its cad plating
this is an important video, anyone that says its a waste of time is wrong.. We've all met the ' i dont have time for stupid questions' types. I'm usually pulling them out of a ditch or welding something for them at 2 am.
im gonna do a video on using a hacksaw blade to hold the fuel pump rod in place or reversing a rear drum, put 3 lug nuts on it and use it as a battering ram to remove the axle, or how about, the screwdriver thru the impossible stuck oil filter...haha.
joe ferguson there's a lot of little tricks to make life easier wrenching
and the filter just tears open with the old screwdriver trick then youre left with a stub to try and remove use a strap wrench and be done as for fuel pumps chevys got a bolt to hold the shaft ive never had to use nothing but grease to hold it on any others and if an axle wont come out i have a beautiful slide hammer that does the job fine
Must be a harbor freight customer!!!
+Mike Secondo Na, I make my own tools.
th-cam.com/video/tnLLGXpVVk4/w-d-xo.html
Lots of good mechanics/machinists buy HF tools for one-off or jobs they expect to do very infrequently. That saves them money so they can buy higher quality tools for jobs they expect to do repeatedly. There's no need to have a shelf full of expensive name brand tools you've used only once or twice now is there?
Mike Secondo lol yep
Buying a 50$ screwdriver doesn't make you a better technician, just like a 200K car doesn't make you a racing driver. You buy it because you can and like to show off. #getreal
I think this was awesome and tips and tricks are ALWAYS appreciated...IGNORE the critics...they usually think they know it all and they actually are the sloppiest
I worked in a machine shop for a number of years after I got out of high school, I remember some old Korean war vet showing me this trick. At the time I thought how silly, Why not just go to the store and buy some. Now that I have gotten older I see how this little bit of work and tricks like this can save you a lot of time.
I don't understand whu you took off the grade 8 marking dont tighten that bolt to tight your strip the internal treads.
+Cory Palmerini This will help.
th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
As a 20-year machinist I was one of the ones that believed this video was common sense. After watching your "Exposed" video, I understand where you were coming from. Everyone's not journeyman machinist or mechanics. Nice videos.
+Jason Barefoot Thanks Jason.
I am that OLD MECHANIC ... hehehe .
+TheZemun Yes you are!
... just kidding.
+TheZemun ;)
i'm an old woman trying to learn how to remove rust from metal
But why change the size of the bolt head
Yeah, I wondered that too.
He was restoring the machine meaning it needed to look oem
He intended to paint the head.
Congrats. You made a grade 8 bolt look just like a grade 3 bolt. Didn't know that was possible. Seriously though chasing the cut threads with a nut already on the bolt does work great.
My dad taught me this one too. Learned it being raised on a wyoming ranch. Works even better if you also have a file and a thread file to clean it up real nice
Um.why do you have to cut it off at all. Not going to hurt if it sticks out 1/4 inch"
sure you could "rig" it that way and it might work or you could take pride in what you do and do it right.
I do this before going to the store regardless. Great tip though . But just the tip!
+SHRED CT Just the tip.;)
SHRED CT just the tip!!!! Ahhhh
Ave has the best tips
+Adam Hughes But only the tip;)
and only for a minute.
use a blunt hacksaw like a man !
Hacksaws always worked for me unless the bolt was harder than the saw blade. :) Then I use a grinder or file to bevel the last thread or two to 45 degrees just like they did when they made the bolt.
Good tip, thanks. Using a measuring ruler can help to identify the length.
Smart! In Gunsmithing, when we don’t have a particular specialized screw, we make one to specs. Your vid is a reinforcement! Good for you! Keep doing great work! Semper Fi
+Robert Mercado Thanks brother!
Great video, thank you
+JON Gergeceff Thanks JON!
you his brother lol
boy am I glad an old mechanic taught you that, because if this is something you make a youtube video out of I'm pretty sure you definitely wouldn't have figured that shit out on your own.
I never thought of using a grinder. Hacksaws work but screw up the threads and leave a sharp edge that you have to file. I'll have to give this one a try.
What type of tool and fitting did you use to polish up the bolt please?
Iam in total shock that u actually made a video! about that.....i thought for a moment that this was some sort of joke or prank!!! BUT u are SERIOUS!!!!......DUDE THAT'S JUST NORMALL EVERYDAY SHIT!!!, I cant count the amount of times ive done this in my 45 years of working!
It works without using the nuts as well, but yes, placing those two nuts ensure you will never screw up the threads plus you get it done quicker, otherwise it might not work from the first attempt. Good to know. Thanks for sharing.
+inox1ck You bet.
th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
Wowzer! The idea of cutting off a too-long bolt with a grinder or Dremel tool had just never occurred to me! Thanks for the incredible wisdom!
Chasing the threads! I have a great hack for you! Dab a small amount of valve grinding compound on your screw tips especially Phillips heads! You keep the screws nice and you don't bugger up your drivers! I even add a small amount on my stones for sharpening certain knives and tools like chisels! Really, you won't believe it!
my go to--is vice grips and the bench grinder--then the air cut off. but we get to the same place. Snickering --great minds. I'm a tad OCD--have even finished em off with a hand file
What “pads” or wheels did you use for the cut off, polishing the marks off and the flats. Looks like there were at least three different ones. Red, green, yellow etc.
+John Icenhower They are from norton.the product line is blaze. Their rollock scotch bright is the best I have used.
th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
I figured this trick out for myself about 10 years ago! Having the nuts on there automatically straightens out the last few threads and lifts the thinnest threads that need to be filled down so they don't hang up and block the threads when you go to thread it in it's intended hole!
+William Robinson Awesome!
th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
I've been doing that for 50 years my grandpa showed me. Those old guys never threw anything away till it was used right down to the nub. Great tip for those who don't know. One comment, I am not certain what that blot holds on, but I doubt they made it a weak bolt just to be cheap. I'd say that cast part ain't cheap, so if it's a choice between stripping the threads in the part, or breaking and removing a bolt, I'd prefer breaking the bolt. That Grade 8 you put in there will tear the threats out of that cast part long before it breaks should someone over tighten it. Just a thought.
You shortened a bolt. Well done, you're a modern day Isambard kingdom Brunel!
I remember when me and this guy were changing the starter motor on my car (conveniently placed under the intake manifold), and he said to me "If you can't find something that fits, make something that fits."
This is a good idea and will work good if you use the same grade Bolt the problem with a harder grade Bolt is somebody will over tighten the bolt in that casting and will strip out the threads in the casting then you really have problems. If you strip out the threads on a bolt you just replace the bolt.
+Walter Glenn Greer We got that covered. It will be in the build video. Thanks for watching Walter!
This might interest You!
th-cam.com/video/hmy96VUTxZo/w-d-xo.html
Amazing. I never would have figured out how to shorten a bolt if it wasn't for TH-cam.
That was Amazing!!!
All that grinding and the Bolt NEVER GOT SO HOT THAT U COULDNT TOUCH IT!!!!
+gwm3591 Stop yelling and I will tell you the secret... Norton blaze.
Simple effective. I love it. A 20 second video would be enough to demonstrate this. Thx
+Ahmed LAHLOU Thanks!
Great video. ¿What grinding wheel did you use to reduce the bolt length, kindly? (¿A flap 36 grit disk, as for a hand angle grinder?). Just wondering. Thank you.
Thanks for taking the time to post this. I’ve always shortened bolts with a hacksaw and then cleaned the end threads up with a triangular and flat file. The nut and abrasive disc worked well, real clean. I’ll try this next time,Cheers 🍻
Phew....Glad I learned something I learned about 20 years ago. I am pretty sure EVERY guy who works with nuts and bolts KNOWS this.
Good video man! I hate seeing all the negative comments...you could pass out bags of cash and some would still complain how ugly and heavy the bags are! lol! People need to realize that this is an educational video for someone who is a beginner or simply looking for different ways to do things. Keep up the good work and don't let haters get you down!
+Andrew Walters th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
I did something similar with some all-thread when a superong screw was needed to fix a commercial washing machine coin mechanism.
What possible reason was there for grinding the grade markings off the head of the bolt? Also a cutoff wheel on your die grinder is much faster and easier.
Nicely done, sir! McGyver's got nothin' on you. 😎
By Grinding & sizing the Hex Bolt, you have damaged the zinc coating top coat and zinc layer, which will make the bolt more prone to rust
Why grind the top and flats on the hex head? Trying to match the other rusted hex heads maybe? FWIW you can bevel the end by holding it at about 45 deg pointing down on a stand grinder wheel. Just a few light touches while turning the screw. This makes for easier starting in tight places.
I will try to remember this, I usually thread on a die and then cut, but sometimes you dont have the right tap/die.
I find it almost impossible to get the threads aligned exactly when trying to cut the threads so this works except for a very, very short bolt lol.
+mike dee th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
I'm curious. Why, since you have 2 nuts to take off, didn't you just use a SLOW cut from a saw?I how it is a hard Bolt, but that was a lot of grinding. When done, 'twirl' the cut edge on a 45 degree lightly and the net will screw off and on by hand.
+John Wade th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
Just carry on with the vids dude. Ignore all the negative comments. If only one person learns something you've done your job!
So how are you going to fix the buggered up mounting threads when your grade 8 bolt destroys them? A Grade 2 bolt was used for a reason and grinding off the Grade 8 marking won't make it a Grade 2 bolt.
Great little hack, and good to pass on these little skills, any reason why you replaced a bolt with a set screw? Just temperary?
I must be dumb , but I don't get it . I get the bit on shortening the bolt , but why go the trouble of changing the head of the bolt , if the threaded section fits through the hole , what is the problem ? is it because you want both to look the same from the outside. ? and I like the green vice. cool colour .

I'm sure there are loads of kids out there that this video helped to learn something new because they lack experience and as the Chinese say "one picture is worth a thousand words". The only problem is that now a days to many of them never get past the stage of looking at pictures and using their heads. So don't hesitate to keep up the Show and Tell.
you can take a piece of all thread or even the threads of a long shoulder bolt,cut to length.take a nut and thread it on but when nut is put on,use a high strength thread locking liquid or a press fit.let the nut be the bolt cap,let the locking agent dry,thread it into the item you want to secure.regardless it will become a jamb nut scenario whether the nut jambs against item or another nut is used on the other end.
I figured this out when I was in highschool on a sunday when everything was closed. Except I cut the bolt instead of grinding it down. Why grind the markings off the top tho?
Nice how to.
Thanks for taking the time for making the video.
What a fantastic trick to teach the younger generation of DIY's. I would stress that some form of corrision prevention needs to be added to the bolt head and threads before installation. Thank you for sharing and great job.
I learned this trick using my imagination when some one gave me bolts that were too long, The first time I did it I cut one the threads did not work. So then I tapered and deburred the cut and the bolt went right in and worked. As for the top part of the bolt I would just leave it alone most of the time
Been doing that for 50 years. Old machinist taught me in 60's
An old mechanic taught me if the bolt doesn't loosen when you turn it, turn it the other way!
That mate should be ya next video.
Just beveling those freshly cut edges makes it work perfect almost every time, even without chasing the threads.
+darryn frost th-cam.com/video/OgvQKuCOhqI/w-d-xo.html
Thanks for posting. Don't mean to sound negative, but wouldn't it have been a lot quicker to give the old bolt a wire brushing and clean up the threads with a die (if you had one) than spend all that time mucking about finding and shortening another one?
Haha nice, just showed me a way to fix a special tool used to repair Hydra Cell fluid pumps, thanks man
even older mechanic taught me a trick many decades ago. you just melt steal and pour into a cast shaped like a bolt. its a pretty dope trick. just passing it on.
