3/4-10 x 3 1/2 Alloy Steel Socket Head Cap Screw helps maintenance and engineering teams source an alloy steel internal-hex screw with verified head-size data. The size callout supports bill-of-material consistency when machine frames and brackets cannot accept a substitute fastener. Applications often include machine tools, production lines, and assembly equipment, especially where counterbored or close-clearance mounting is required. Socket engagement helps technicians apply installation torque from above the head in constrained layouts. The technical highlight block below retains the verified head diameter, head height, body diameter, and hex key data. Technical Highlights Material: Alloy Steel Thread: 3/4-10 Length: 3 1/2 in.
