One tool I use A LOT is my RTD 48 Master Rethreading Kit.
With everything made in CHINA these days, thread quality has gone down hill!!!
The other day we got a new livingroom set. When I was putting the legs on the chair, one of the nut certs was buggerd. I went to the garage and broke out my kit. Within a few minutes, they were good as new and I was sitting in my new chair.
Thanks Snap On!!!
