5/16-18 x 1 1/4 Alloy Steel Socket Head Cap Screw gives engineers an internal-hex fastener for mechanical joints where socket engagement and dimensional consistency matter. The exact 5/16-18 x 1 1/4 size helps buyers align the fastener with stockroom identification and purchasing review. Applications often include manufacturing cells, fixture design, and precision assemblies, especially where counterbored or close-clearance mounting is required. Alloy steel supports strength-focused fastening where clamp load and repeatable assembly are important. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 5/16-18 Length: 1 1/4 in.
