• Cylindrical Head Socket Cap Screw

    Socket cap screws have a small cylindrical head with tall vertical sides, and with recessed hex-shaped sockets with which to drive them. Because they are driven with hex keys (Allen wrench) or hex socket bits, they are ideal for applications where limited clearance would not allow the use of wrenches and sockets. In addition, the driving surface is protected from external damage and provides six sides of contact surface for added torque.

  • Flat Head Socket Cap Screws

    Socket cap screws are commonly used in machine parts, die fixturing, and clamping. The flat socket head enables driving where there is not sufficient space for wrenches or sockets, and allows the screw head to sit flush with the surface.
    Socket cap screws are available as either an alloy with a blackened oxide finish, or as stainless steel. Also, they feature either coarse (UNC) or fine (UNF) threading.
