  • 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 design allows more torque to be put on the fastener while reducing fastener rounding and allows the user to more easily turn worn, rounded or rusted fasteners
