[TowerTalk] U Bolts for TX-2 Rotor

[Jerry Kincade]

Very true, but one caution probably should be added. Anti-seize or any other
type of thread lubricant will take away much of the feedback you normally
expect to get when cranking down on a nut to the point where it "feels"
right (and you're scared to go any further!). This reduced feedback just
when things are getting very tight makes it easy to overtighten and break
something, so some extra caution is in order. Metal experts claim even a dry
galvanized (zinc) coating flows and provides lubrication under pressure, and
Rohn and others recommend caution when tightening galvanized hardware for
that reason. Most grades of SS are also simply not as tough as standard
Grade 5 bolts, which of course compounds the problem. So where possible, a
little threadlocking compound and less "crankdown" muscle is appropriate. I
learned some of this the hard way on my tractor, where I got a lesson in
using large size easy-outs. :-)
