1-8 x 3/4 Alloy Steel Socket Head Cap Screw helps maintenance and engineering teams source an alloy steel internal-hex screw with verified head-size data. The 1-8 thread and 3/4 in. length support repair work tied to an existing fastener callout in high-clamping-force joints. The screw is useful across engineering departments, assembly equipment, and packaging machinery when a compact internal-hex fastener is required. 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: 1-8 Length: 3/4 in.
