• Satin finish provides corrosion resistance and a slip resistant grip

• 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 flare nut box end, minimizing slippage
