  • Allows for fine indexing, helping to improve speed and access
  • Offset handle helps keep knuckles clear of obstruction to help save time

  • 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 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 box end, minimizing slippage
