------------ REPLY FOLLOWS ------------
Stainless steel nuts and bolts will work fine, but be sure to do two
things:
1. Use a locking nut, the kind with a nylon insert. If you are really
paranoid about loosening, also use Loctite threadlocker. Do not rely
on lockwashers alone.
and
2. Apply an anti=sieze compound to the threads before tightening.
Stainless steel has a nasty habit of "galling", where the surface
deforms under pressure and causes the nut to jam, making further
tightening and/or removal impossible without breaking it. Your local
hardware store should have them, or a google search will find lots of
them.
