1/2-20 x 3 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. With a 1/2-20 thread and 3 in. length, it fits machine frames and brackets where size interchangeability matters. Common uses include tooling, machine tools, and manufacturing plants, where internal hex installation helps keep the joint accessible. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. The technical highlight block below retains the verified head diameter, head height, body diameter, and hex key data. Technical Highlights Material: Alloy Steel Thread: 1/2-20 Length: 3 in.
