Works great! I messed up a internal reverse thread. Got me out of a costly repair. Marked adjustment knobs and internal thread tool with corresponding paint just to make it easier.

This little tool is a great all in one thread repair kit. No need to search through multiple thread pitches. Fix specialty nuts or bolts. Perfect for on the road repairs or in my case on the trail repairs when things go wrong.

The external thread tool is spot on. Does exactly as you would expect. The internal tool has a little to be desired but does work fine. The internal tool has little thumb sockets that you need to operate it. Not sure why they aren't made onto the tool. Also I wish you could take the bar out and put a ratchet on them. All in all very happy with it.
