3/8-16 x 8 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. With a 3/8-16 thread and 8 in. length, it fits machine frames and brackets where size interchangeability matters. It is frequently used in robotics, precision assemblies, and maintenance repair when socket engagement is preferred over external-wrench access.
