1/2-13 x 4 3/4 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 exact 1/2-13 x 4 3/4 size helps buyers align the fastener with service work where the exact thread and length are already defined. The screw is useful across power transmission, machine tools, and manufacturing plants when a compact internal-hex fastener is required. Alloy steel supports strength-focused fastening where clamp load and repeatable assembly are important. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 1/2-13 Length: 4 3/4 in.
