[TowerTalk] Galling and seizing of SS nuts to SS threaded

I have used blue Loctite 242 with smaller stainless steel screws on
antennas and I have had no galling issues.  I have not tried it on larger
boom u-bolts.  One concern, especially if you are on the tower, would be
installing all of the u-bolts and evenly tightening them before the
Loctite sets in the hot sun.

##  I have never tried Blue loctite on SS hard ware.   Are you also using 
nylocks with the SS bolts + SS screws...or just  SS regular nuts ???
Can u even use loctite with SS nylock nuts  ?
What else that might work is purple loctite.  I have never used it, but
apparently its slightly weaker than the blue stuff..and may well be ideal
for a
lot of various applications.
What I would not recommend is red loctite.  Red loctite  is as good as
welded....esp with SS machine screws...  you cant get em out.
