3/8-24 x 8 1/2 Alloy Steel Socket Head Cap Screw is a socket head cap screw for buyers matching an exact thread and length to drawings, repair records, or stocked hardware. The size callout supports service work where the exact thread and length are already defined when production-floor assemblies cannot accept a substitute fastener. Common uses include manufacturing plants, industrial automation, and industrial facilities, where internal hex installation helps keep the joint accessible. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. This exact size supports industrial hardware, repair, and production requirements.
