I need to shorten a couple of gun cleaning rods. Found that the thread was an odd one - 32 tpi (no problem with this) but the OD is 0.153, which falls between 6-32 and 8-32. Machinery's Handbook doesn't list a 7xanything thread. IS there a #7 machine screw size? I guess that's why we have lathes - but a die would be nice to clean up the threads.
