I know this topic has been beaten to death, and most use black oxide for their motor mounts. I am using stainless hardware for the mounts to the stringers and stringer feet to the stringers..... My question is. McMaster Carr has stainless hardware in the lengths I need in 18-8 stainless, is this comporable to grade5 steel? Is it less, or better?

Selection to choose from
