Corrosive environment and conductive grease?
Hopefully Mexicowonderer will chime in. I don't like bothering people with PM, but if Mex isn't reading now, I'll have to :) I have aluminum bus bars where plated set screws got stuck to the bar r...

With a toothpick dab a minute quantity of genuine (aluminum) NEVER SEIZE onto the threads of each set screw. Smear it around to cover the entire threads. To protect the completed assembly I use a coat of ANHYDROUS LANOLIN which comes in a jar available at your local pharmacy. It works far better and far longer than the commercial al/cu stuff at the hardware store.
You have to be careful with the combination of aluminum (tin coated) and copper. Some compounds react negatively. Charging what NoOx does for stupid cosmoline is a crime.
Aluminum should be shined brilliant then coated almost instantly afterward with protector compound. Once aluminum oxide starts to form it does not stop. One of these days they are going to get smart and start flashing critical aluminum parts with gold. Get the Au out of the hands of speculators.
I learned a lot having a hotel within 50 meters of the crashing tropical (28c) Pacific Ocean surf. The school of the hardest knocks.
You cannot do this with aluminum but with brass or copper, coating the material with 100% Pb (lead) is the cheapest way to make things last. Tin sucks. It is barely better than bare copper.
But where steel threads into aluminum my experience is Never Seize has no peer.
