- 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
