I doubt it's a question of strength. I've never sheared a rack bolt, & I've carried some heavy loads. I prefer stainless for it's better corrosion resistance but have never had a carbon steel bolt rust in place either. Note there are a couple of grades of stainless that vary in corrosion resistance. IIRC, heat treated carbon steel that is grade 5 or higher (often referred to as "aircraft grade") is stronger than stainless.
