Quickly and easily remove damaged or rounded nuts and bolts. Place socket on fastener and turn with ratchet, breaker bar or T-handle. Grip on fastener tightens as more torque is applied. No hammering is required to install socket over fastener. Use on all types of standard nuts and bolts as well as studs, pipe nipples, and corroded auto and marine fasteners. May be used for “best fit” on metric and fractional fasteners. May be used with air or electric impact wrench for extra speed and turning power
