Thank you for this video! I knew I had to tap a hole on my vehicle and bought a tap and die set. Opened it up and had no clue! Now I know which part to use for tight places! Thanks again! An explanation of how to use the thread finder tool(s) is all that's missing.
Great job making this video. I found it very helpful. I needed to tap a hole for the exhaust hanger on my car. Thank you.
To know which size to use:
1) Buy some thread pitch gauges and a caliper.
2) The markings (for material grade/strength) on the nuts and bolts can help you determine if the measurement is a metric or SAE. Other words for SAE is standard or American.
3) Some hardware stores have free measurement tools along the nuts and bolts section where you can insert your nut or bolt to check for size. This is the easiest way to find the size, but will only have common sizes.
4) You can also search for common bolt and nut sizes by searching for torque spec charts for nuts and bolts. These charts can give you an idea if you incorrectly used the caliper and thread pitch gauges, which can certainly happen. Using these tools take PRACTICE.
I asked my question, then saw this post. Thank you for that info. This is a catch 22. Two concerns would be 1). What if you screw up the first pass? How do you correct that? Got to the next size up?....and B). How do you practice something like this?? This is a fascinating skill, given the possibilities it can open up. I suppose there's a third question... What if you're in a fabrication scenario, and you want to make a threaded hole, yet the hole isn't drilled yet? Sorry for the "noob" questions, but I just came across a scenario like this, and wondered how it was resolved.
@@phillamoore157please answer all those 3 questions for me. Very interesting
Wow thank you for explaining so simply. I searched up and down the internet....finally I get what tap and die means. Some people say it so complicated jeez.
Thanks for this video! I’m getting a set tommorow to fix my meat grinder and you’ve shown perfectly how to use one
Omfg thank you sooo so much for this video I had a bolt hole on my 2000 Camry water pump that was cross threaded bc of u you are gonna make this car keep running on the road cheers mate u earned a sub 💪💪🙏🙏🙏❤️
god I wish they had this as an app for my iphone so I could tap and die lol
Did u find the app?
I'm So DePpReSsED
Good camera work!! Thank you!
I was curious what these tap and die set was. So I youtube it and this video was one of the first ones that I seen. Very interesting and good job installing those fog lights.
+David Young Thanks. It's a pretty good set. I don't really use it very often, but for jobs here and there it's perfectly fine. This set was purchased from Harbor Freight.
How do we make a boyfriend
Fantastic work as usual
robertd10481 Thanks man
Thinking about getting this reel from a guy pretty cheap but the foot stripped off the real still has the foot but the threads are completely stripped do you think I would be able to Re-thread the holes and put slightly bigger screws in??
Awesome video
You should talk about sizes of the bolts and the threads bro
Its labeled in the set what you're using.
Wouldn’t it depend on the application?
OMG! THANK YOU FOR GETTING STRAIGHT TO THE DANG POINT! Very helpful!
This was a super helpful video, now I can tap out a socket on our wood burning stove here in minus whatever temp Vermont!
Glad I could help!
Great video. I'd like to find a chart that shows what drill to use for which size die cut you want to make.
Thank you 👍👍👍
Glad to help.
Everytime I try screwing in the thread tap tool, the tool will turn but the tap wouldn't even when I screw it all the way in. Is there a way to fix it or put it on a wrench.
Are you suppose to drill out the old threads when sizing up?
Good video but you forgot to explain what size drill bit to use for the right size tap and forgot to explain what thread standard or metric ..
Yeah I know right
exactly! The hardest part if figuring out the correct tap to use!
There are charts online re drill bit sizes which I have on my mobile phone, it’s so infrequent that I need to use a tap or die that I forget. I think all M series bolts are metric as are the fittings on most cars. He didn’t show how to find the thread count through or explain the different taps for through holes and bling holes. I think this reply might be teaching my grandma to suck eggs though and you probably know a lot more than I do.
GREAT video....but, how do you gauge what size to use? I would think a hair bigger than the hole, so the die has some material to bite into. But, that's just the guess of a mere mortal....
I have that same crappy set I got it off of eBay many years ago but it has served me well
Nice way to get out of a jam.
Would've been nice if you would have explained which size(s) drill bits to use for the "Tap" bits...
Hi, good video....
Question? so i will drill off and i have to shoose the size?? thank you, good job
Exactly. Choose a size that's similar to the old bolt and tap away.
Is there a 9/16-18 on this set?
About to use mine for the first time. Just wanted to make sure nothing tricky about using the tap set. So the m6 x1.0mm tap is used for a hole drilled using a 6mm drill bit. Is this correct? and the 1.0mm is the thread spacing?
I don't think he knows
Richard Fox = many thanks....I will follow up on it..
fantastic splash screen and logo
Thank you! Appreciate the feedback
When you tap new threads into a part in my case (MTB crank arm for a pedal) will it make tap original threads it will it make it larger?
I believe it must be upsized. If you didn't have to drill it out and could use an internal rethreader then it would stay the same.
Good stuff
Thank you.
Hello how to get this kit or box I am from Iraq please
awesome video bro n thanks for the tips would u recommend matco or snap on tap n die set
Thanks man. You can't go wrong with either brand.
CarsNToys well what would you buy the 117pc master set snap on or the 76pc matco set
Can you use a ratchet for spinning one full rotation, then backing it off?
+ATR Footage Factory Sure man!
Footage Factory Yeah, some of the tap holders come with a 3/8” drive for fitting you’re ratchet or extension in 👍
my hero
how would i go about re threading a reverse thread? threads aren't damaged or anything just need it to tighten clockwise not anti clockwise
easy answer, you're screwed.. but taps and dies are made for "left hand" application... but they would be hard to find.. ahh but wait, there is the internet!!!
Hey man can i do this to the holes where my valve cover screws go? Its not the screws that are stripped, its where the screw goes which are the holes.... i have a valve cover leak due to this and its probbly why my check engine light is on as well
Did you figure it out? Im going through the same problem right now
@@MrSpookytaco did u figure it out? Same situation lol
retreading a new strip hole. How do you know which one will fit in the hole is correct size?
+Darkmand8 I drill out the old bolt and just choose the next size up to tap with.
I have the same cheap and nasty 60 piece tungsten Savage Performance kit
Is it possible to do this, upside down, into a chassis? Or is the metal too hard/thick?
Probably just take awhile but it should work
Is it possible to rethread the same size again? For example an M6 to M6 using this method?
Yeah to touch up a thread but it still have to be in decent shape.
tanks from iran
There is something I don't quite understand about taps and dies (have never had one in my hands).
Both tools seem to have cutting faces, outwards, or inwards respectively. Threading cuts spirals right? How do these tools cut spirals instead of parallel circles when you turn them? And how do they cut spirals in a way that makes nuts and bolts match exactly? That is, that both spirals have the same exact angle?
How does Posey track work, why is the sky blue
@@illhaveanother4365 lol
Why are boobs good? Who knows
FUCKED up, when you turned on the hellish noise! Why-no DAMN neeed!
Almost thought the first shot was easier to see, but good vid
Thank you. Hope it helped.
great video, waferdick some of us are not rich not going to spend 300 on taps die set Harbor freight works just fine as its not a matter of life and death. if I were to blow money on tools it would be craftsman.
Thank you
Yeah man I love my Craftsman tools too but honestly sears is closing and I dunno if I’ll be able to redeem the lifetime guarantee easily anymore.... I use Kobalt now for the Harbor Freight lifetime warrantee stuff
Lifetime warranty on the Matco taps and dies.Mac warranties theirs too
Once rethreaded, can I still use sane size of bolt that came off or do I need to go to bigger size
Same question
@@chadron44did you figure it out?
Awesome vid
+jmoyet Thank you
I feel very proud after seeing ur video
boss work thanks
Glad to help.
Can you increase the size of the hole from m6 to m8?
Yes, in most circumstances.
Can you use WD-40 as cutting oil?
I think it would be better than nothing, but you should use like CRC or Tap Magic
Hey can I use WD40 as a cutting fluid?
It's certainly better than nothing. Spray the bit and the part you're working on. Good luck.
you're not "re-threading", you're cutting new threads
Shut your mouth 🤐
I did rethreading using tap method. But I used the wrong size. Can retread it again on top of the retread I already did?
Also you don’t need to put spring in it after you rethread?
Getting started can be real difficult if the initial thread is badly messed up, torn, crushed etc, go real slow.
Good point. Slow and steady.
Man that set is polpular.seen it on several vids and its the same one I purchased from the Amazon.
It does the job.
CarsNToys Indeed it does.
Well
bro said Sears and i realized wow this video must be from a while ago huh
can you just put it in a drill and go slowly?
Did this come from Walmart?
Sterling Witherspoon looks like harbor frieght
"Last a lifetime"...my lifetime was 5 mins
Bummer.
If you don't have cutting oil can you use wd40?
Piero Duilio from my research, best to just use cutting oil
I think backing out after a few turns just gives you an opportunity to cut the next thread at the wrong angle. Might be better just to keep going
A Hammer. Do you know what a hammer is?!
?
Comedy... I see what you did there!
i got a Snap-on tap and die set for $30 :D
That's awesome!
John I organized my late father's tool box after we moved recently and found his almost new Snap-on tap and die set in it's case. That was nice. I should look up the value, but it's priceless to me. It was just cool to find a full set of nice Snap-on tools. Also found a Snap-on drill motor and driver, but they connect to an air compressor, no cords or battery. I gotta start looking up all the tools we didn't use over the years, as most projects were pertaining to woodworking/finishing.
Is this how you make a silencer thread on a gun?
it would work yea, but you need to do make sure you have enough room to make threads
Gonna go purging?
Can you start from the South.
@imgone What?
@imgone Trump isn't racist
@First Last No he doesn't, Go away russian /cnn troll

Sears?
You forget to say what size of tap you need for what size of hole...?
+mario agostini It's different for every job. I try to tap a new hole that's close in diameter to the stripped out one.
+mario agostini If you want to be precise you can always use dial calipers on the stripped screw/bolt to get the diameter and then if you have enough thread left on the bolt use the pitch gauge that comes with your tap & die set to see what tap you need to use. or like CarsNToys says ball park it and do one size larger.
mario agostini You can find conversion charts on google that gives you the info you need. Like what size tap to use with certain size drill bits etc... 👍
Could do without the lousy music!
I still don't understand why you have to turn around and walk away quietly when you see someone with these tools out.
You don't use a regular tap and die set to repair messed up threads threads.Use a rethreading tap and die set.Don't buy the tap and die sets from Harbor,junk.Irwin is a better choice.A regular tap and die set is made for making new threads only.
wafrederick what bout northern tool + equipment? Ace hardware?
Would not buy from Northern tool and equipment.Ace Hardware sells Irwin.My Matco set is made by Irwin which cost me $300.00 which the taps and dies have a lifetime warranty on them.
wafrederick
so ace hardware is a go? how bout home depot or lowes? or should I look for independent stores that sell quality premium tools?
Online and certain auto parts stores sell Irwin
Wrong!
My grandfather wants to know why you're wearing his wife's dishwashing gloves to do a man's job.
Thank you.
@@CarsNToys :)
You need medical latex gloves for this? What; don't like to get your hands dirty?
They look medical but they're not.
Music is awful
Appreciate the feedback.
How to retap a hole, not how to rethread a hole. This works fine if you can use a larger bolt or if the threads are warped but not completely ripped out. If you have no threads left and need the same size bolt to fit, you need to rethread the hole. Also you talked way to much. this video should have been 5 minutes tops.
Appreciate the feedback.
You have to stop talking with your hands. They are all over the place and tapping on things. I couldn't watch the video past about 2 minutes.
Could do without the lousy music!
