5/8-11 x 2 3/4 Alloy Steel Socket Head Cap Screw gives engineers an internal-hex fastener for mechanical joints where socket engagement and dimensional consistency matter. The 5/8-11 thread and 2 3/4 in. length support service work where the exact thread and length are already defined in actuated equipment. It is frequently used in machine tools, robotics, and maintenance repair when socket engagement is preferred over external-wrench access. 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: 5/8-11 Length: 2 3/4 in.
