SK Hand Tool Corporation has expanded its socket offering with three new 1/4" and 3/8" Drive TurboSocket sets in both fractional/metric sizes. SK's most unique socket line, the new TurboSocket design works to improve socket grip as more torque is applied. These made-in-the-U.S.A. sockets easily remove damaged or rounded nuts and bolts with no hammering involved. Simply place the socket on the fastener, and turn.
