Socket Head Cap Screws


Socket Head Cap Screws are threaded fasteners with a cylindrical head and a recessed hexagon drive. Also known as Allen head screws, socket screws are turned by using a hexagon-shaped key and can be tightened to much higher torque specifications than a crossed recessed or slotted drive fastener.

Socket screws are often used in applications with insufficient clearance to use a fastener with an external hexagon head.

Benefits of Socket Head Cap Screws

Fewer socket head cap screws are needed to achieve the same clamping force in a joint compared to ordinary fasteners. The lower number of screws leads to a weight reduction in the finished product. Additionally, as fewer screws are necessary for a given job, fewer holes are required to be drilled and tapped.
