What type of screws (or nails) can be used to fasten a copper metal sheet .020 thick?
Question:I don't want to the two metals to react. The copper sheet is .020 thick and is 12"x24". I want to fasten the copper sheet to a wood frame. I am wanting to know what screws or nails to buy. This is for an outdoor application.
Answers:
use zinc coated wood screws with a neoprene washer - only tighten them to snug so you don't rip the washer. Punch the copper so the hole stays small.
Copper would be fine.
Look up the table of dissimilar metals. The further apart the metals are , the more of a problem.
Copper on copper is fine.
You can purchase copper nails or brass screws. Neither will react with the copper.
Outdoors use Galvanized screws - they are non-reactive to wheather.
use brass screw or plastic screw.
