If you're concerned with corrosion, you can always switch entirely to stainless hardware, but the typical black oxide fasteners are fine as long as you use some antisieze/grease on the threads.

dude...:
im not really that bothered about, i was just wondering if zinc was more prone to cold forging to the aluminium in the stem (or something like that), than the regular black oxide coating. the stem came with zinc coated bolts is all

i grease the shit out of all the bolts on my bike but this thing was not budging at all, i guess i must have overtightened cos it launched out of there when i sawed through the bolt (the head is still in my lounge somewhere, i dont know where it ended up it shot off that fast).

One of these



Stick a piece of sacrificial metal on it? I wonder if you had a Magnesium stem plate if it would prevent it?

this is where its at.

I've tried to switch to all stainless steel fasteners anywhere I'm contacting aluminum on my bike.  They just look good and don't gall as readily.

The Navy uses stainless in aluminum anywhere things are exposed to seawater. I don't usually resort to "it works for XX, so it must be good" arguments, but seawater and aluminum is a motherfucker, and of the numerous problems crossing my desk, stainless fasteners are not that common, so I'm buying it.
