Special Order - Details




• 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.
