1/2-13 x 9 1/2 Alloy Steel Socket Head Cap Screw provides a strength-focused alloy steel socket cap screw option for mechanical assemblies requiring this exact size. The size callout supports service work where the exact thread and length are already defined when machine frames and brackets cannot accept a substitute fastener. The screw is useful across maintenance shops, packaging machinery, and automation systems when a compact internal-hex fastener is required. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 1/2-13 Length: 9 1/2 in.
