5/16-24 x 6 1/2 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 high-clamping-force joints cannot accept a substitute fastener. It is frequently used in power transmission, maintenance repair, and maintenance shops when socket engagement is preferred over external-wrench access. Socket engagement helps technicians apply installation torque from above the head in constrained layouts. 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: 6 1/2 in.
