1 1/2-6 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 1/2-6 thread and 3 in. length, it fits high-clamping-force joints where size interchangeability matters. Industrial buyers may specify it for power transmission, manufacturing cells, and packaging machinery where head geometry and drive access need to be predictable. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 1 1/2-6 Length: 3 in.
