Re: Stainless nuts bolts in Aluminum boat

[legendre]

This is going to draw flames, and there are numerous grades of "stainless" steels.. but..

Typical SS is really a junk material for high-stress fasteners.. I’d avoid it, if at all possible. In particular, SS nuts on SS screws have a very annoying tendency to gall and lock-up under heavy torque. You’re better off with quality galvanized steel hardware, some anti-seize and a shot of paint.

This is just my experience, YMMV.
