TurboSockets® quickly and easily remove damaged or rounded nuts and bolts. To properly use TurboSockets®, simply place the TurboSocket® on a fastener and turn with ratchet, breaker bar or T-handle. The TurboSockets®’ grip on a fastener tightens as more torque is applied and no hammering is required to install the TurboSocket® over the fastener.TurboSockets® can be used on all types of standard nuts and bolts as well as studs, pipe nipples, and corroded auto and marine fasteners and may be used for ‘best fit’ on metric and fractional fasteners. TurboSockets® may be used with air or electric impact wrenches for extra speed and turning power.
