A lot of times when working on a project it’s easier to just replace a bolt or stud rather than restore it. However, sometimes you come across a hard-to-find bolt or you just don’t have time to run out and find a replacement so restoring threads is easier.
Whether your bolt is cross-threaded or has threads that are flat, there’s a fix. The first tool you could use is a thread file, or thread restoring file. This tool actually has 8 different sizes of thread pitch on it, everything from 11 up to 24. Taking the flat threads and running it over the file will get rid of them.
If you have a cross-threaded bolt a die from a tap and die set installed in a t-handle will do the trick. Simply tighten the die in the tool and run your bolt through it.

i wondered if its possible to cut a threadtap in Half, clamp it together in the middle of a bold where the thread is good and "straithen" out the thread to the damaged end?
has someone tried this befor???
What if u can't get the die started on the bolt? Do u put the wide end of die on 1st or 2nd?
Absolute gang member!!! Thank you!
don't you need lube?
Is there a quick way to reduce the thread size (i.e from M4 to M3)? I've done it a few times with these die sets but it feels harder than it should be.
Or you got a steering colum that needs it lol
I do lpve the internet trolls in the comments…😂
What’s best to use for a bolt that is bulging at the end because someone hit end of it with a hammer?
wonder how you restore the threads in the hole the bolt screws into
What if my bolt was messed up from the tip and the nut wasn’t going in ?
this is what we start with in shop class.
I thought it was going to be some new school technique or fancy new tools. Just old school everyday normal stuff that any mechanic proffessional or diy should know
