Proto® 3/4" Drive Socket 1-9/16" - 12 Point

Proto 12 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. Ball detent design. Made of heat-treated alloy steel. Side locking hole.
