Ordered M24x1.5 hex die to freshen/salvage the thread on a CV joint hub. It works as intended. $34 for one, Chinese-made tool, which will probably sit in my workshop drawer for another 10 years, unused. Take it or leave it, I was unable to find anything locally, and replacing the hub would easily cost close to $100.It does seem pretty robust, though. What I like is that it's thick enough to turn it with a large wrench onto. I didn't have any box wrenches or adjustables big enough to accomodate it, so I wound up using a monkey wrench. Not my best moment, but the job got done, and my BMW is back together.The hex dies that have the recessed area and matching bad reviews seem to be for smaller diameter threads.

Solid product that solved my issue!
