Stainless steel is more electropositive than carbon steel. You will get bimetallic corrosion. That is to say, the stainless steel will not rust, but it will promote and accelerate rust in carbon steel to which it is attached, compared to using carbon steel to attach to carbon steel.
Grade 8 hardware has 50% more tensile strength than stainless steel hardware. Grade 5 hardware has 20% more tensile strength than stainless steel hardware. No comparison.
Stainless steel hardware sounds good at first blush, but you probably don't want to go there.
