[TowerTalk] replacement bolt for Rohn Thrust bearing DE K0FF

[K0FF]

Dave, the problem in both applications is not backing off but rather
breaking during installation due to the increased force applied to the
threads. Remember the old mechanics axiom "tighten it till it squeaks). If
you lube the nut, the squeak is replaced with a snap (as the bolt breaks). I
guess the proper sequence would be to "tighten until the bolt breaks, and
then back off 1/2 turn".

Anti Seize may be one of those products like Cutting Oil. It works without
actually lubricating. If it's made for the purpose, I'm sure it's fine, but
don't try it with WD-40.

On the otherhand, I always bath a nut that's coming OFF, with WD40.
Slathering goo on the exposed threads of an already tightened bolt and even
the nut is a good idea.

PS I used to work in the Police Radio shop in St. Louis, and it was located
in the Police Garage. You could always tell a new-hire in the tire
department by the cursing going on when he snapped a lug he had lubed.
Funniest Cop story I ever heard was an officer was driving down the street
and saw a tire and wheel go whizzing past his car. Upon looking around,
there were no other vehicles, so he decided to stop and investigate. The
instant he tapped the brake, his car nosed in and the front crashed to the
pavement. It was his own right front tire. All the lugs broke off. I'll bet
the pedestrians thought a 3 wheel vehicle was a new Police invention, until
is crashed!
