Steve,
Stainless Nylock (or any other ss shakeproof nut) on stainless bolts is an
invitation to galling, metal-to-metal welding. If the parts are perfectly
clean, they will gall every time. I *do* use the stainless Nylocks, but I
smear a little lubricant on the bolt threads first - Vaseline, silicone
grease, gun grease, whatever - the self-locking properties of the nut don't
seem to be compromised long-term. Stainless hardware is wonderful, but
hanging off a tower with a hacksaw in one hand will give your vocabulary a
thorough workout!
