Sonic 12-point sockets offer a better angle-of-attack than 6-point sockets, twice as much. These shallow-well sockets are made from touch Chrome Vanadium steel and the small knurling at the base of the socket provides a little more grip for your fingers. Sonic 12-point sockets are available in 1/4", 3/8", and 1/2" drive options, and they are covered by a Warranty.
