I have used stainless in a few places, but when I do, am careful to use a sparing amount of anti seize on the threads. I dont think I would use stainless in this application because not only can stainless gall, causing the fastener to seize, but also because stainless alloy has lower torque and shear specs than steel. I would be interested to see the eBay listing michael1954 used for his screws.
How much torque and shear strength does it really need to retain a cover?
Galling tends to be a problem with similar metals in contact with each other. As long as one is harder than the other, galling shouldn’t be an issue.
