Re: (ET) stainless steel

["SteveS" <ssawtelle fcc net>]

I agree about cautious use. I also stay away from SS where the original
fastener is a high grade bolt.

BTW, I've been selecting 316 SS when available due to it's anti-corrosion
properties.The magnetic SS types are stronger but less corrosion resistant.

So to sum up, SS probably will give better protection in the ET with the
caveat that it is weaker and may gall.

Thanks for the input - I was getting ready to order a bunch of SS fasteners
from McMaster, but wanted to poll the collective wisdom first.

is
A2.  The strength of these fasteners is between Grade 2 and 3.  Stainless
steel is a fairly soft metal and for this reason it tends to gall.  Always
use Anti-Seize or a similar product when working with stainlss steel
fasteners!  If you have never had a stainless fastener gall on you before,
it's not fun.  When a fastener galls, it seizes.
