I'm not saying ss studs WON'T work, and the torque required is minimal - Just saying that all metal expands/contracts and all metals and grades react according to their inherent composition. These studs manage to loosen on their own accord as it is. Changing unnecessarilly may result in more tinkering than is required. Also - but highly unlikely to occur in this application - I have seen fasteners with less than required specifications literally explode when overloaded. As a result, I personally avoid pissing with fasteners when possible. It's just my opinion and there is little doubt you'll disagree.
