What (if any) lubricant can I use on a screw/nut to keep it from
binding over time? I may not need to loosen the nut for a decade or
more.

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.

Anti-Seize, available at any good hardware or industrial supply store.
There are a few different varieties. You can also get it at

Most are good to 2000 degrees, but there is a high heat that can go to 2900
degrees.
