5/16 inch length Socket Cap Screws (ASME B18. 2.1)

Socket Head Cap Screws are typically used in machine parts, die fixturing, and clamping. Socket head cap screws have a flat faced, circular raised head with an indented hex socket. They can be fully or part threaded, are usually manufactured from high grade alloy steel. Dimensionally, metric socket head cap screws are covered by the relevant DIN, ISO or JIS standards, but US/Imperial socket head cap screws are covered by the ASME B18.2.1 and B18.3 specifications.
