Our stainless steel is all Marine Grade 316 Stainless Stee (A4). The higher nickel content in our 316SS alloys makes them more corrosion resistant than the 304SS (A2) and 18-8 alternatives. Upgrade to 316SS if your fasteners will be used in a marine environment or other corrosive environments.
The “stainless”, but not the actual alloy, is often sold by big-box stores. The fasteners in question are not the 316SS required for marine applications. Fair Wind Fasteners only deals in fasteners that we would use ourselves. Marine Grade Stainless Steel
