Product description

Socket Head Cap Screws, or Socket Cap Screws, are threaded fasteners with a cylindrical head and a recessed hexagon drive. 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 cap screws are often used in applications like machine parts, die fixturing and clamping where there is not sufficient space for wrenches or sockets.
