Thanks. My dad just died, he left us all the tools. His buddy came over the other day and tried to buy this huge rethreading kit and I told him no, I might need that. Well, a month later, here I am today, definitely needing that lol and so glad dad left amazing tools for me. Thanks for this video, it taught me a lot. Time to go fix what I messed up now.
Very well done. I've known of HeliCoils since high school but never seen one installed. Very good explanation along with excellent camera/lighting work. Thank you very much.
Sir, this is awesome, you made this seem so easy and saved me so much money in re-threading the insert coil for my lawnmower which was stripped. Right now my lawn looks like the amazon. Finally I know exactly what I have to do! right after church tomorrow, i'm stopping by the Home Depot and picking up this Heli Coil. You're the bomb Sir,! Thank you so very much for posting!
Enjoyed this and explained what others had not - "breaking the tang" Thank you now I know. Furthermore, I am led to believe from my research the new threads are even slightly stronger than the old ones ! Keep making informative videos like this.
Followed this video. Was always afraid of screwing up this type of repair when I had to one day cross that bridge. Worked like a champ. I did have the luck of someone telling me which kit to use, but I wasn't sure. Anyways great to the point video!!
Very old video but still relevant. What do you do about the tang when it’s a blind hole such as the lower unit of an outboard? Can’t risk the loose piece of steel from the tang getting into the gears, bearings or seals.
I know this is old but in the early 70s I gave up on these and went to using time serts. Much better and stronger and do not come back out. Used them my whole career and past as a mechanic and shop owner.
Another option, grab brazing rod. braze the hole, then drill and tap. If it's something that won't come in contact with too much heat. You can use plumbing solder or silver solder to fix threads, then drill and tap. It worked for me.
What’s the tool called that you use at 4:00 to cut the thread? It attaches to the top of the thread tap. I bought a thread repair kit but it doesn’t have this.
thank you sir... i really appreciate the time and effort you put into this video and the knowledge you share so willingly with the world..... diy rules....
with these coil kit isertion tool im thinking it will be 2 short to insert the helicoil hench my hole id deeply located below another pilot hole any thoughts?
How would I go about installing a helicoil on a hole that is not threaded all the way through, but only at the end (the bolt is only threaded like 1/2" in from the tip)? The bolt is for an oil filter cover on a bike, the hole goes all the way through the case cover so I can simply take the cover off to reach the stripped threads, but can helicoils be installed reversed? I'm too dumb to work out how the threading would work out :(, I assume it would just be like a nut and work both ways right?
So....If I wanted to use this method to repair a spark plug hole on a riding mower I would have to remove the head first or risk that tiny tab that is broken off not blowing out of the cylinder????
We generally drill suitable BSP tap hole bigger size than that of damaged tapping, then tapping it with BSP tap & fixing threaded bush with retainer compound LOCTITE 643.
I dont mean to be off topic but does anybody know of a way to log back into an instagram account?? I somehow forgot the account password. I would appreciate any tips you can give me!
@Samson Andre thanks so much for your reply. I found the site through google and Im in the hacking process atm. I see it takes a while so I will reply here later when my account password hopefully is recovered.
So if my M10 head bolt has to drop about 5 inches ( 127mm) before reaching the last inch or so of now stripped threads I can come back with six inches worth of HeliCoils so that the entire length of the bolt hole becomes threaded?
Great video! Do I have any options if one of the threads actually breaks off on a bolt? This is on a cylinder head stud bolt and happened because my torque wrench was acting up and I ended up over torquing it and breaking one of the threads.
you have the best videos on this topic by far every body just about like time serts i would think once the bolt corrodes it would take the time sert out when you take the bolt out. i use the heil- coil have been for years.
Not sure if you are still monitoring this but hopefully so! I need to replace internal threads that holds the bolt for the hydraulic arm on my car's hatchback. Would the coils work? It appears that whatever held the threads before is gone, broken off into the frame of the car. Now I am left with a flat piece of metal with a hole, and nothing on the inside to grab or support the coils. Would I first insert some sort of tube to hold the coils? Thanks!
I would insert a steal tube and weld in place grind it flush then use the Helicoil but if you're doing that you sometimes can find threaded collar drill out your hole weld in the threaded collar and grind flush run a tap through it to make sure the top parts of the threads aren't boogered-up
Great demo. Thanks for share such good vedio. I need your advise. I have engine block aluminum and head cylinder bolt threads gone. So one option to oversize with new bolts.another option to install helicoil insert. So what is the best to do so? I appreciate ur help and advise. Thanks
I'd like to hear their reasoning on the Heli-Coils. Every industry that I am aware of uses Heli-Coil at least for repair work, some to reinforce new theads with them.
Helicoil is just inherently a frustration, I’m never satisfied with it, it’s not liquid tight, it pulls out easily, Time-sert is so much better than helicoil I just quit helicoil entirely. The problem with most people nowadays is that they don’t so their own research, all they do is listen to what other people tell them what’s good, and think that’s the only option. I’ve seen so many people use snap on torque wrenches thinking it’s the best, while Stahlwille Manoskop makes snap on look like harbor freight. But I guess that’s a good thing, if everybody does their own research how do I get to be competitive?
Superior Use a tap to see. Check the bolt that came out. Sometimes a standard bolt size and a metric can be very similar. A Time Sert kit is better. An Autozone kit is good. Use a thread pitch gauge to check sizes. If the threads don't match up, it could be standard and not metric. A thread pitch gauge should match exactly to the size.
Dario de nero Actually, you might come across a situation where you don't know. Run a tap into the hole. One that seems to be the right size might do. It could be metric. Standard and metric can be close. Check the bolt if it's there. An Autozone kit is better.
Dario de nero Sometimes a person might come across a job they aren't sure what size it is. Metric can be very close to standard. A thread gauge can show that. What if the bolt isn't there. A insert size can be changed from stand. to metric and met. to stand. Or small to larger. Once you determine what size you want, then you can install the insert. I've used helicoil. A drill bit can be used to determine aproximate size. It depends on the bolt type if it's special.
I accidentally stripped the aluminum threads on 2 bolts on the underside of my truck's sidesteps... Aluminum strips sooo easily. Thankfully not any of the ones that are actually bolted to the frame. The tubesteps themselves are completely secure, but I might buy one of these kits and fix the 2 that stripped. :) Looks pretty straightforward. In fact, why don't they put steel coils in aluminum threads from the factory like this, to secure them? They're rather inexpensive.
The only trick I could see, would be trimming the top off. As it is running down a tapped hole, the second would be in alignment with the threads, hence no issue. I would also add a drop of LocTite when installing the insert, but that's me..
The cutters de[pend on the corect size hole and many of the tqaps come with a drill bit. I would not try just tapping out an existing hole wioth ANY tap unless I knew for sure that it was the correct diameter.
Easley one of the tops you-help vid's I know. ... thanks I stripped the stud bore hole on the head of a dirt bike. 250 2-stoker. The specs are close fit threads. Are heli, or others, good enough for high vibration environments? I see them used on drag racing motors so I would think so, but I am not sure.
hola amigos tener en cuenta lo prácticos que son los helicoidales para materiales blandos y para recuperar agujeros pasados de rosca pues para poner el helicoidal se debe de hacer un taladro mas grande ...también para zonas que estos tornillos se tienen que quitar y poner muchas veces pues son templados los helicoidales
ive used helicoils for fucking up worse a stripped out hole in my dirtbike cylinder head, the set i used wasnt helicoil brand but it was 50 bucks so what the fuck?, the tap was great and all but when it came time to put the spring in the hole the damn part of the spring that stuck inwards would just straighten out on the tool that is supposed to put it in and the tool that puts it in got gulled up and rounded off and everything else, just a pain in the ass for me and in my area it seems you can only get bull shit ones that aint worth shit, maybe they work for other people but my experience with them doesnt instill alot of confidence in them, btw im not the heroin addict that stripped the threads out, i got it used for 150 bucks (whole bike) and it runs great all accept blow by on the spark plug, and i wanted to fix it before the plug blew out in the middle of nowhere and now im fucked, if i had a tig welder i could fill it in and drill out and re tap it but im just a piece of shit teenager with no job and no real tools and it will be a while before i get a career in welding and all that bullshit where the money is made and i dont have to go out and buy a new cylinder head every damn time i get a chinese apollo dirtbike for a damn good deal, i could just jb weld it in the hole but what if the plug goes bad, its just a damn mess, they make inserts for it that are steel tubes threaded on the inside and out but i fucking doubt anybody around this gay ass city has them or even anything i could use to fix it. . .hate yuppies and their "throw away and just buy a new one" culture, it means alot of free lawnmowers but it also means there isnt a lathe within a 10,000 mile radius if you need to borrow one
Helicoils are a god send, unfortunately the company I work for now doesnt like them. I dont know why apparently they dont like them in the mining sector at all 8(

the most useful video on youtube about tapping bolt threads
By far the best video I've seen on this topic.
Agreed, very to-the -point and complete.
yes I vouch for this vid. its great with lots of detail and thank you
Very old video but still relevant. What do you do about the tang when it’s a blind hole such as the lower unit of an outboard? Can’t risk the loose piece of steel from the tang getting into the gears, bearings or seals.
Well done. Thank you! This helped me repair my Willys exhaust stud. It was one that went into the water jacket. Worked great.No more leaks!!!!
Thank you for this video and your explanation. You taught me several things and reinforced others that I had learned before.
what do you call that device with handles that you put the die into; it has set screws? I have the dies but nothing to mount them in.
I know this is old but in the early 70s I gave up on these and went to using time serts. Much better and stronger and do not come back out. Used them my whole career and past as a mechanic and shop owner.
What happen to snapped heli coil tip?let it stay inside the hole?
Another option, grab brazing rod.
braze the hole, then drill and tap.
If it's something that won't come in contact with too much heat.
You can use plumbing solder or silver solder to fix threads, then drill and tap. It worked for me.
What’s the tool called that you use at 4:00 to cut the thread? It attaches to the top of the thread tap. I bought a thread repair kit but it doesn’t have this.
Adjustable tap wrench
great stuff can you tell what size of tap i need for 25/64 drill bit like you used here
Precise instruction and editing. What do you think about repair taps and repair dies?
Good stuff. You're a natural at teaching.
How to cut them if we don't have the right seize length?
Really appreciate the effort you put into your videos. Thanks
thank you sir... i really appreciate the time and effort you put into this video and the knowledge you share so willingly with the world..... diy rules....
very well made, thanks for your support in helping others do things the right way!
Is it okay to use this method at oil sump cover? No leaking afterwards?
Excellent- very good explanations and accompanying video to make this very easy to understand.
Thanks! Really needed this! Now I can work on the spark plugs and valve cover of my car!
with these coil kit isertion tool im thinking it will be 2 short to insert the helicoil hench my hole id deeply located below another pilot hole any thoughts?

A bolt chipped off in the hold can you make a video of how to remove it
So....If I wanted to use this method to repair a spark plug hole on a riding mower I would have to remove the head first or risk that tiny tab that is broken off not blowing out of the cylinder????
Thank you! This video is the best one I have found, it explains everything perfectly and now I can perform my repair. Thanks again!

@Samson Andre It worked and I now got access to my account again. Im so happy!
Thank you so much you saved my ass :D
@Donovan Crosby Happy to help :D
after re threading the hole, can the bolt be put into the hole without helicoil?
So if my M10 head bolt has to drop about 5 inches ( 127mm) before reaching the last inch or so of now stripped threads I can come back with six inches worth of HeliCoils so that the entire length of the bolt hole becomes threaded?
Thank you for your very informative and clearly audible video! Very helpful unlike some other videos on here :)
Great video! Do I have any options if one of the threads actually breaks off on a bolt? This is on a cylinder head stud bolt and happened because my torque wrench was acting up and I ended up over torquing it and breaking one of the threads.
6mm thread broken. Make new hole 8mm and replace new thread for 6mm or 8mm?
THE BEST USEFUL VIDEO I'VE SEEN.FOR MAJOR REPAIRS
This must be the guy who does the Rockler commercials as well many others. He always does a good job.
Definitive and well presented , great cadence to your narrative.
where i can but these
Thanks a million!!! This video was as perfectly precise as your drill press. Kudos!
Hu you are not the same I will
I have a hole I'm trying to retap. The bolt size is M6-1. What drill bit and tap will I have to use to retap this hole???? Thank you in advance.
I have a inside threaded. the outside bolt is m12 by 22 long. which size should I use to fix the inside threaded. size 13??
Is there a trick to stacking the inserts? How do you do it?
wonder if heli coils would work for like a bulldozer transmission ..most of them are cast so its not as easy to weld them up drill and then tap
you have the best videos on this topic by far every body just about like time serts i would think once the bolt corrodes it would take the time sert out when you take the bolt out. i use the heil- coil have been for years.

Gosto e trabalho com esse material "Mais não sei como é fabricado" Tem alma restrição??obrigado!!
Great video! Earned a new subscriber 👍
Why the insert at all and not just re-tap the hole with the proper tap size ? Thank You

Helicoil repair kit with a few inserts, 1 instillation tool and 1 tap = $68, i bought a 60 piece tap n dye set for $24....
Thanks for the clear presentation. Much appreciated.
Helpful video, thank you for sharing sir !
Awesome vid, very helpful and informative !! Thanks.
Great video. Very informative
If you threaded the hole with the same threads as on the bolt.
Nice done man!
nice tap wrench.
it usually happens at the weekend when the shops are shut sod's law great video
yes the hole is 14mm*1.5mm and I am using a tap of 14mm*1.5mm...I guess it should work eh? I have ordered helicoils 14mm*1.5mm*1.5D just in case
Thank You Great Video.. I learned a lot in this video..
字不要顯示卡中間
Compared to the cost of replacing what you can fix with them HeliCoils are just about free.
Thanks jesse venture
Time-sert kits are better. They lock in. The installation tool with that kit can break off. An Autozone kit is better!
Thank you. Great instructional
Very good video!
Good video 👍

fuckin right on man
You could do stand up comedy
Good stuff, thanks much!
Thanks dude good vid!
I mead aheil coil in my hoom
Thanks for the video, a great upload!
Thanks for a great video
Well done
Good job, thanks for this video!
good video man
Hey I couldnt agree more I love them myself but for some reason my boss at my new job cant stand them.
Nice video
Thank you!
Helicoils are a god send, unfortunately the company I work for now doesnt like them. I dont know why apparently they dont like them in the mining sector at all 8(
