1/2" Drive Deep Socket 31mm 12-Point Chrome Vanadium Steel Impact Socket - Perfect for Automotive Repair, Machinery Maintenance & DIY Projects

Stanley J5331M Proto 1/2-inch Drive Deep Socket 31 mm - 12 Point Proto 12 Point Sockets are ideal for use on stubborn or damaged fasteners and also on fasteners made from soft materials. The Torque Plus design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners. The Torque Plus 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 Torque Plus internal design minimizes fastener rounding, helps to extend fastener life and allows the user to more easily turn worn, rounded, or rusted fasteners. 1/2-inch Drive Metric Deep Sockets - 12 Point 31mm Size 1-39/64-inch Nut End Outside Diameter.
