in a situation like that i would think spending a few
extra bucks on stainless would be worth while. some of
our engineer friends here might post with some good
advice,but off hand, i would look into epoxing in
stainless threaded rod (provided you have access to an
air compressor to clean the holes). i just don't trust
espansion bolts for critical connections.

I have never seen tables on stainless verses bright steel but I
know with stainless screws, they twist off twice as easy as bright
steel so you might want to up the size one notch to compensate for
that to make them equal to new steel.
