1/2-20 x 7/8 Alloy Steel Socket Head Cap Screw is commonly used where an Allen-style socket drive is preferred over external-wrench hardware in confined equipment layouts. The exact 1/2-20 x 7/8 size helps buyers align the fastener with service work where the exact thread and length are already defined. Applications often include packaging machinery, tooling, and robotics, especially where counterbored or close-clearance mounting is required. 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: 1/2-20 Length: 7/8 in.
