I did just that drilling for a clevis pin which is much more convenient that torquing down a jam nut anyway. But I never subjected mine to such abuse. But the compressors I have used made from hardware store all-thread tend to gum up the threads after only a couple of uses. This one is still good as new. And I have a spare piece of acme thread (the shortest piece I could buy was twice as long as I needed).<br>

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.</span></font></font></font></font></font></font></div>
