Proto® 1" Drive Socket 2-3/16"- 12 Point

Proto Spline tools are designed to service high tensile strength fasteners used widely on military and commercial aircraft. 2-3/16-in Size. 3-5/64-inch Nut end outside diameter. 2-13/32-inch Drive end outside diameter. 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.
