This ensures specific tensile strength and rupture properties. For the most critical applications, we also offer fastners per ASTM A453 Grade 660 specification. ![]() In addition, A286 / Alloy 660 is also non-magnetic and finds a niche in non-magnetic cryogenic equipment. While they should not be used for strong acid environments, they provide excellent oxidation resistance up to 1500☏ (815☌) in conditions that would typically be found in high temperature exhaust streams.īecause of the properties of Alloy 660 / A286, these flat head screws are often found in high temperature engine, manifold, exhaust and turbine applications as well as off-shore oil & gas applications. As a result, A286 screws provide high levels of strength from room temperature up to about 1300☏ (700☌).Ī286 flat head screws are also mildly corrosion resistant. A286 flat head screws are known for their high strength, creep resistance and oxidation resistance at elevated temperatures once age hardened.
