1-64 x 3/8 Alloy Steel Socket Head Cap Screw is suited to assemblies that need an alloy steel cap screw for clamp load, service access, and compact installation. The size callout supports stockroom identification and purchasing review when socket-drive service locations cannot accept a substitute fastener. Applications often include fixture design, assembly equipment, and machine tools, 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: 1-64 Length: 3/8 in.
