In the 36 years that I've been licensed now --- and actively homebrewing,
too, I hasten to add! --- I have never, ever had any problems of corrosion
due to steel screws coming into contact with aluminum, etc. etc. ...never!
It's an absolute non-issue, in my books, unless --- as you say --- one plans
to build something, and then instantly store it away in a damp basement for
a decade, or more (at which point, one ponders the question, "...Then why
even bother to build anything in the first place...?!").
