  • Allows for fine indexing, helping to improve speed and access
  • Non-reflective ProtoBlack™ finish for use where non-plated products are required
  • Box ends incorporate the TorquePlus™ system
  • Fits 4, 6 and 12 point fasteners
  • 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
  • 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
