A286 Button Head Cap Screws

A286 button head cap screws or alloy 660 stainless steel button head cap screws are known for their high strength, creep resistance and oxidation resistance at elevated temperatures. This iron-nickel-chromium alloy (once age-hardened) provides A286 screws with high levels of strength from room temperature up to about 1300°F (700°C). A286 button head cap screws are mildly corrosion resistant. While they should not be used for strong acid environments, they provide excellent oxidation resistance up to 1300°F (700°C) in conditions that would typically be found in high temperature exhaust streams. Because of these properties, A286 button head cap screws are often found in high temperature engine, manifold, exhaust and turbine applications as well as off-shore oil & gas applications.
