Product Features
| Remarks | • Proto® Tethered Tool Sockets are 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. • Proto® 12 point sockets are 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. | Country of Origin | USA |
