PROTO® Full polished socket set. 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. Sockets 12 piece, Ratchet 3/8 inch drive standard length classic pear head 7 inch, Extension 3/8 inch drive 3 and 6 inch. packed with blow-molded case. ASME B107.1.
