A286 Lock Nuts

A286 nuts, also known as Alloy 660 nuts are stainless steel alloy which contains iron, nickel and chromium. A286 lock nuts are known for their high strength, creep resistance and oxidation resistance at elevated temperatures once age hardened. As a result, A286 nuts provide high levels of strength from room temperature up to about 1300°F (700°C). A286 lock nuts are also mildly corrosion resistant. While they should not be used for strong acid environments, they provide excellent oxidation resistance up to 1500°F (815°C) in conditions that would typically be found in high temperature exhaust streams.
