Hmm, so my box of "gold screws" (which I guess are galvanized) say on the

"Gold" fasteners are usually cadmium plated and not galvanized.
Because they are 'plated' rather than 'dipped", they do not have
enough coating to avoid the corrosive effects of ACQ pressure treated
lumber.
....more likely zinc plating with a "gold" dichromate rinse.
