I'd use stainless bolts with a bot of antisieze to prevent galling

I wouldnt have thought galling was a problem, if you didnt do the bolts up too tight.

You'd be correct Bonz but it pays to be a bit ahead of yourself. Disimilar metals can do funny things sometimes

OK..wot's 'galling"..????

Bonz (Vic) posted:

Galling is the process whereby two metals are brought together at high pressures (like doing a thread up really tight) and the two surfaces, in this case the bolt and the nutor threaded surface "weld" together, sort of like a cold weld. Vibration can then break these tiny weld further increasing friction between the surfaces and making them VERY difficult to persuade to part company.
