1/2"(3/8"-16) x 1 1/4" Socket Shoulder Screw, Black Oxide

• 

The 1/2"(3/8"-16) x 1 1/4" Socket Shoulder Screws are distinguished by an unthreaded section called the shoulder located just below the head. They have a raised cylindrical head similar to standard socket head cap screws. These fasteners are installed using a hexagon drive tool, which makes them useful in tight spaces where standard tools may not fit. The shoulder section provides a smooth, precise surface for components to rotate or align around. Black oxide is standard and readily available, offering a minimally protective layer.
