[TowerTalk] ROHN TOWER BOLTS

[Charles Gallo]

Nyloc nuts are great (as are "jet" aka "k" nuts) but be careful re stainless. Look at rated strength vs say a grade 8 nut. A jet nut has a 160000 psi strength, where you are talking 85k-100k for stainless

Also if using SS, be sure to use never seize compound, if you don't, the nuts will almost for sure seize up if you try to remove at a latter date. Lesson "hard learned" with SS bumper bolts on my Hot Rod!!!

>>   One other point on the tower hardware from Rohn these days.  They have changed their hardware where the nuts are designed to be put on the bolt ONE time.  To remove the nut, one will damage the thread of the bolt (sorry - forgot the description of this design - lock nut?).  Guess the concept is, you put up a tower one time and never take it down!  However to their point, it prevents nuts from backing off (good thing).
