5/16"-18 UNC x 0.50" Shoulder Screw, Silver Plated
Inconel 718 (ASTM B637 N07718). Machined to the customer's drawing in our Houston shop.
5/16"-18 UNC × 0.50" long shoulder screw (0.375" OD × 0.875") to ASME B18.3 in precipitation-hardened Inconel 718 per ASTM B637, silver plated per MIL-QQ-S-365D Type 1 Grade B, .0005" thick.
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 →
