[TowerTalk] Galling and seizing of SS nuts to SS threaded studs and bolts.

[Roger (K8RI) on TT]

I have, or had? a 12" T handle about a foot long, but there us now a 
socket wrench that ratchets available in the big box stored and many 
hardware stores. I think the one brand is Cobalt. They seem well made 
and have a nice finish.
