5/16-24 x 1 Alloy Steel Socket Head Cap Screw gives engineers an internal-hex fastener for mechanical joints where socket engagement and dimensional consistency matter. This size keeps the specified 5/16-24 thread and 1 in. length visible for repair work tied to an existing fastener callout. Common uses include industrial automation, precision assemblies, and machine tools, where internal hex installation helps keep the joint accessible. Socket engagement helps technicians apply installation torque from above the head in constrained layouts. The combination of product name, size, material, and verified head data improves search clarity for engineers and buyers. Technical Highlights Material: Alloy Steel Thread: 5/16-24 Length: 1 in.
