Tether-Ready Drive Deep Sockets, 3/8 in Drive, 17 mm, 2 3/4 in L, 12 Points

Features : Manufactured with four detent holes so that the pin detent will engage correctly regardless of the direction the socket is placed on the square drive | The Positive Control System requires a separate tool to attach or remove the socket, meaning it cannot be removed without specific intent | Chrome finish is applied after the holes are bored for better corrosion resistance | Ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials | 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
