Tether-Ready Drive Deep Socket Sets, 1/2 in Drive, 12 Point, Inch

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.
