Wrecking a bolt stinks, especially if you don’t have a spare handy. But who carries a whole set of dies with them? That’s when having a ThreadMate in your toolbox could be a life saver. As you rotate it around the damaged bolt, the undamaged threads guide the cutting blade to repair the rest.

This mechanical thread restorer will work on any bolt with any thread pitch from 5/32′ to 1/2″ (4mm to 13mm). Switching between right and left handed threads is as simple as changing the order of the blades. You can also remove rust, scale, and paint with the ThreadMate, breathing new life into old hardware.

ThreadMate is manufactured by Shilo Technologies, who’s just in the beginning stages of marketing in the US, so the ThreadMade can be difficult to locate.  Right now, Garett Wade has it — as well as a version for internal thread repair — in stock for about $40.  For other options, give Google a try.

    Griots Garage has had this item in their catalog for a while now at $24.99. See it at:
    I have wanted one but hadn’t ordered one yet. Should probably get one before I need it.

    I saw a similar item at Lee Valley, $24.50:

    I have a tough time justifying roughly $25 to fix bolts that may cost, at most, few dollars new. I guess if you constantly destroy bolts, it may become cost effective.

    I worked with an experienced mechanic who had one of these that was passed on to him from his father, so this is not a new idea. It’s great when working on machinery from obscure countries that use bolt sizes that seem to be neither standard or metric, or when you need to have something up an running in 10 minutes and don’t have time to run to the hardware store for a new bolt.

    The thing it has on a thread chaser file is that it is only one tool for all those bolt sizes, instead of several…

    Yeah, but does it match all the different thread profiles as chasers can be purchased for? or does it just have a one size fits all cutter? I just want to remove the deformities, not reprofile the thread.
    Different thread standards have different pitches and angles
    I don’t always deal with UNF( which even has differing profiles of fine through coarse i.e. UNC, UNF,UNEF,and UNS), but have to deal with on occasion, BSW,BA and UTS.
    Not saying I’ll not try one out, gadget freak that I am. Just that I’ve found that the K.I.S.S. principal is usually best, It may be handy, but a one size fits all is seldom the best tool for the job.

    I usually carry just 2 multies, KD tools 2228 for metric and 2229 for SAE

    Also not limited as to size of bolt. and they are only about $10 a piece.

    Administrators, what’s with all the spam?

  6. oilstain says:

    Wow, why was this one so heavilly spammed, is it the word Thread in the title or what? Weird, international spam of all sorts!

    Mitch, I’m pretty sure the moderators don’t actually moderate around here. Remember the auto-reset bug/feature that drove everyone nuts? It took months for them to remove it.
