I have a set of galvanized hinges for a shed door. The shed is located 50 feet from the ocean. Very salty air.

The hinges didn't come with screws and I'm having a hard time finding suitable galvanized screws, though I can easily source stainless steel screws for them.

I understand that in general, mixing dissimilar metals can accelerate corrosion.

Will this cause a problem for me?
