If it gets to that point, it wont matter anyhow. studs or bolts, you wont be able to get them out and the flanges will be shot, too.

I wouldn't worry too much about it, unless you fell like changing them out with bolts and nuts, that you will in turn change out every so often again to prevent corrosion. It will take many years to get THAT bad.
