ATM install

[ATMkiosks]

I'm installing an ATM into a thru wall environment. The ATM is powdercoated painted steel, fastened by stainless steel screws to stainless steel side wall flashing trim. Will the powdercoating be enough to minimize galvanic reaction caused by the stainless steel. Or is there something else we should consider?

Actually, screws are grade 5, not stainless

Powder coating will work for the ATM, but the screws are in trouble. If they become wet, then they will rust, and then they will contaminate the stainless and it, too, can corrode where the rust stains damage its passive film. Get stainless screws and you'll be OK, if there is no bare metal on the carbon steel ATM where it contacts the screws.
