" PRO " Stanley Proto J5016B 3/8-Inch Drive Deep Socket, 1/2-Inch, 12 Point, Black Oxide

Stanley J5016B Proto 3/8-inch Drive Deep Black Oxide Socket 1/2-inch - 12 Point Black oxide finish - hand use only. Proto 12 Point Sockets are ideal for use on stubborn or damaged fasteners and also on fasteners made from soft materials. The Torque Plus design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners. The Torque Plus 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 Torque Plus internal design minimizes fastener rounding, helps to extend fastener life and allows the user to more easily turn worn, rounded, or rusted fasteners.
