Item Package Quantity 1The box end of most Proto wrenches incorporate the TorquePlus wrenching system. The TorquePlus design is a high performance drive configuration which allows for quick and easy wrench engagement to the fastener flats, not the corners. The configuration employs a radius-corner design, shifting contact area and stresses over a large area of the wrench, minimizing slippage. The internal design of the TorquePlus minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turnworn, rounded, or rusted fasteners.
