[TowerTalk] Fwd: Lockwasher Comparison

[Roger (K8RI) on TT]

I agree.  Over the years, ROHN has tried several approaches and I've 
tried a few. I even used SS and wished I hadn't. Even with Never Seize 
after many years, I've had them become one on occasion.

Galvanized bolts are ungraded AFAIK but you don't need grade 8, or even 
grade 5 in shear. Double galvanized, ungraded are fine and the nuts do 
come off only when needed. Never forget to use a taper pin punch to 
enlarge the bolt holes to a snug fit if needed. Never thread the bolts 
through the hole in the tower leg and never drill them out! (ROHN's 
instructions)

I've never needed a lubricant, or Never Seize with ROHN nuts and bolts.
