Copper clamp rust

[avtuvy]

Hello,
I used the clamps listed below to attach 1/5 copper pipe to wood studs, the clamps are attached to the wood with sheet rock screws.
I noticed that some of the clamps are covered with rust, I assume that it is going to be a problem in the future and it might be because I used steel screws. What is the correct way to do that?

the name tells the story, copper PLATED STEEL

what you have is called electrolysis or dissimilar metals,

and brass screws

Thanks
That's what I thought, I saw online that Nibco U624 is listed as copper but it does not say if it is solid or plated, please help with that
Are there special brass screws to use, or any brass screw from home depot can be used?

use a magnetic, copper will not stick, copper coated and steel will.

walk over to the level section, borrow a level, it has a magnetic on the 9'' torpedo levels

any brass wood screw, pre dill the wood, so it will not strip the head
