by Loctite, Bostik, ND Industries, Nylock, 3M, and Permaloc.  The only down
side is they are not effective in high temperatures (from 450 to 200 degrees

Subject: Thread Locking

Any thoughts on good ways to lock up threads?  

I have some steel eyebars packed on a pin with recessed pin nuts holding
them in place.  The pins are about 3" in diameter and they are exposed to
weather.  I don't want the nuts to loosen, of course.  The options I can
think of are thread-lock compound, tack-welding, and burring the threads

Is there a reliable thread-lock compound (besides rust)?
