1/2-13 x 1 3/4 Alloy Steel Socket Head Cap Screw is specified when a machine assembly needs a high-strength alloy steel socket screw with predictable head and drive geometry. The 1/2-13 thread and 1 3/4 in. length support service work where the exact thread and length are already defined in actuated equipment. The screw is useful across maintenance repair, industrial automation, and precision assemblies when a compact internal-hex fastener is required. 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: 1/2-13 Length: 1 3/4 in.
