3/4-16 x 2 3/4 Alloy Steel Socket Head Cap Screw is commonly used where an Allen-style socket drive is preferred over external-wrench hardware in confined equipment layouts. The size callout supports service work where the exact thread and length are already defined when fixture clamps cannot accept a substitute fastener. The screw is useful across industrial facilities, engineering departments, and packaging machinery when a compact internal-hex fastener is required. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 3/4-16 Length: 2 3/4 in.
