[TowerTalk] Rotator screw sealing.

[Grant Saviers]

I agree with Bryan, properly applied Loctite works extremely well. I 
attended a short Loctite seminar (nice cause they gave out lots of 
samples) and learned that generic Loctite "cures" when oxygen is absent 
and iron is present.  The tubes are oxygen permeable so never transfer 
the contents to another container.  There are also primers available to 
insure the curing.  There are formulations available for other fastener 
materials.

The stud idea suggested on this thread is a neat way to go and I will do 
that in the future.  The rotator aluminum housings have limited strength 
and life, so a "permanent" SS stud is has many benefits.  A SS heavy nut 
plus nylock nut should not come loose and is a lot easier than cross 
drilling bolt heads and using safety wires.
