When I was designing missiles and bombs, we used a polyimide epoxy
primer on stainless screws in aluminum. It acted both as a barrier coat
(faying surface sealer) and a thread locker. It worked well in products
that had a 30 year storage life requirement. Loctite also makes faying
surface sealants that work well as a barrier coat but tefgel is probably
the easiest to use.

I stick the stainless screws into a tub of Lanacote before
assembly into aluminum and avoid corrosion. The same $7 tub has
served for eighteen years. I keep one on the boat and another at
home. It's now $12 but far cheaper than TefGel.
