What type of threads are used on this compressor? If they are Acme threads you
cannot use a "Jam Nut" since that thread is designed
to NOT lock up.
Try it sometime. I think you'll find that they do lock, just not as tightly as
vee threads. With enough torque, they still lock
pretty tight.
If you want a permanent joint that won't turn even under extreme torque, drill
a hole lengthwise through the threads and drive a
hardened pin into the hole. I used that on a hub puller I built with 1" ACME
rod (using a second nut to lock the first one during
the drilling process), and the nut/rod joint took all the torque I was able to
throw at it, even with a 1" drive impact wrench and
standing on the end of a 6' section of pipe. It literally crushed the rod
lengthwise, but the nut never moved on the rod.
