- Allows for fine indexing, helping to improve speed and access
- Non-reflective ProtoBlack™ finish for use where non-plated products are required

- 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
