Don’t settle for a lesser alloy, all of our stainless steel is Marine Grade 316 Stainless Steel (A4). The higher nickel content in our 316SS alloys makes them more corrosion resistant than the 304SS (A2) and 18-8 alternatives. If you plan to use your fasteners in a marine, or otherwise corrosive setting, upgrading to 316SS from 304SS will prove to be a worthwhile investment.
The “stainless”, but not the actual alloy, is often sold by big-box stores. Those fasteners do not meet the requirements for 316SS in marine fasteners. Fair Wind Fasteners only deals in fasteners that we would use ourselves. Marine Grade Stainless Steel
