• Overmolded protection cap prevents dust and debris from jamming mechanism
• Employs a pin system (versus screw) which connects the central block to the driving end and open end upgrading overall performance
• Proto 6 point sockets are ideal for use on stubborn or damaged fasteners and also on fasteners made from soft materials
• 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 internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded or rusted fasteners
