Proto J77278P Impact Socket, 3/8" Drive, 6 Points, 11/16", Black Oxide, 2-7/64" OAL

• Ball and spring design which allows for a 30-degree working angle
• Smooth 360-degree 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 that 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.
