Re: Digest Number 1243

THere are about a gazillion thread locking compounds out there, many
not from Loctite! Even Loctite has a wide variety of these products,
as I remember. I used one type to hold sealed bearings in a custom
bicycle bottom bracket, which is pretty hard service and involved a
corrosive environment sometimes. I wouldn't use a methacrylate type or
any other that didn't need to be put on before assembly.

This is a major concern of mine. The bolts on my trailer's wheels were tight,
but not frozen. The wheel rims, on the other hand, were "exfoliating" like
de-laminating plywood. Is this a matter where one must back out and re-torque
the bolts on a regular basis? Will this be enough to prevent the threads from
corroding? Should they be "shot" with WD-40 or some other moisture dispersal
agent before re-installation? I used some "Loc-Tite" compound a long time
ago, for a purpose I no longer recall. My recollection is that it dried to a
kind of brittle consistency (i.e. probably not good for moisture exclusion)
and was intended to discourage bolts from loosening, sort of a substitute for
safety wiring or lock tabs, I guess.

There is an article by Robb White on the subject of trailers in the latest
MAIB, but he doesn't address the lug nut/lug bolt issue. Perhaps its not a
problem and I'm worried about nothing? I'd like to know.

The most common brand of "anti-sieze" is Loctite

The "standard" silver colored compound is a "low-temp" application
[relatively]
Premium high temp versions are "copper" and "nickel" filled.
"Wurth" has a good product as well.
General Motors specipically states, "do not lubricate wheel nuts/lugs" as do
many other manufacturers.
Check the manufactures' service info before using on lugs.
Torque specs on "Chevy" are 20 ft lbs, end ports, 26 ft lbs, center ports.

That stuff works too good on exhaust studs. I put it on a set of exhaust
studs for headers on a Vette, and after replacing the studs 3 different
times because they kept backing out, I ended up drilling the heads and
running safe tie wire to keep them from backing out.

Be careful using on things where your safety is at risk of the nuts back
out, especially on lug nuts.

I was given a bottle of this specifically for using on the spark plugs of
my airplane.
