Proto® 1/2" Drive Universal Impact Socket 17mm - 6 Point

Ball and spring design which allows for a 30° working angle. Smooth 360° rotation. Proto 6 Point Impact 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.
