3/4-10 x 2 1/4 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 size callout supports repair work tied to an existing fastener callout when repair inventories cannot accept a substitute fastener. The screw is useful across assembly equipment, manufacturing plants, and power transmission 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: 3/4-10 Length: 2 1/4 in.
