Stanley Proto J77511MP Proto 3/8-Inch Drive Universal Impact Socket

Stanley J77511MP Proto 3/8-inch Drive Universal Impact Socket 11 mm - 12 Point Ball and spring design which allows for a 30° working angle. Smooth 360° rotation. The TorquePlus design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners. The TorquePlus configuration employs a radius-corner design, shifting contact area and stress away from the fastener corners and distributing contact stresses over a large area of the socket, minimizing slippage. The TorquePlus internal design minimizes fastener rounding, helps to extend fastener life and allows the user to more easily turn worn, rounded, or rusted fasteners.
