5 out of 5 stars review

I cross threaded a lugnut on a 1/2 by 20 fine thread stud and needed to clean up the threads. I was hesitant to buy this because it does not say the pitch of any of the dies in the description or packaging. I bought it anyway to give it a try and it worked perfectly and cleaned the threads in 2 passes.
