3/8-16 x 3 1/4 Alloy Steel Socket Head Cap Screw supports industrial fastening where the socket head, internal hex drive, and verified head dimensions help match existing designs. The 3/8-16 thread and 3 1/4 in. length support service work where the exact thread and length are already defined in counterbored mounting points. It is frequently used in material handling, manufacturing plants, and production lines when socket engagement is preferred over external-wrench access. Verified head dimensions and hex key size help engineering departments check fit before ordering. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 3/8-16 Length: 3 1/4 in.
