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.
