5/16"-24 UNF-3A x 5/8" Socket Head Cap Screws
Inconel 718 (ASTM B637), silver plated. Machined to the customer's drawing in our Houston shop.
5/16"–24 UNF-3A x 5/8" Socket Head Cap Screws, manufactured per ASME B18.3 and Inconel 718 per ASTM B637, with a silver-plated finish for superior performance and durability.
Special socket products are machined from bar where the specification allows, with the socket broached and the threads rolled, or cut where the specification or order allows, then heat treated and plated as the specification requires. Shoulder, low-head, flat-head and set-screw patterns follow ASME B18.3 unless the drawing says otherwise.
About the material: The premier high-strength nickel superalloy — 185 ksi tensile and 150 ksi yield from cryogenic temperatures to 1200 °F, with corrosion and sour-gas resistance to match. Read the Inconel 718 data page →
