1/2-13 x 2 1/4 Alloy Steel Socket Head Cap Screw is suited to assemblies that need an alloy steel cap screw for clamp load, service access, and compact installation. The 1/2-13 thread and 2 1/4 in. length support stockroom identification and purchasing review in actuated equipment. Common uses include automation systems, maintenance repair, and maintenance shops, where internal hex installation helps keep the joint accessible. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. This keeps the listing focused on the fastener geometry rather than broad catalog language.
