5/16-24 x 5 1/2 Alloy Steel Socket Head Cap Screw helps maintenance and engineering teams source an alloy steel internal-hex screw with verified head-size data. For drive components, the 5/16-24 thread and 5 1/2 in. length help confirm the correct socket cap screw before installation. It is frequently used in manufacturing plants, machine tools, and material handling when socket engagement is preferred over external-wrench access. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 5/16-24 Length: 5 1/2 in.
