What (if any) lubricant can I use on a screw/nut to keep it from

?The nut is part of the burner assembly on our range so it is
exposed to some heat (but not direct flame). It also gets some
moisture exposure due to the inherent moisture content in Natural gas.

add routine maintence item, move nut loosen and tighten a little
yearly.......

although your range may fail from other problems before this nut
becomes a showstopper

I'd get stainless hardware, use anti-seize and not worry about it.

Well it's not a regular nut/bolt - it's special hardware both pieces
are bronze also.

The answer is TefGel. VERY expensive stuff, but it is exactly right
for this application, and a tiny bit goes a very long way. I use it
for things such as mounting stainless hardware with stainless screws
into aluminum spars on my boat, in a salt water environment.
Ordinarily, that would be a recipe for horrendous corrosion. TefGel
solves the issue.
