Abstract
A torsion socket includes a longitudinally extending torsion shaft and a nut socket fashioned at one end of the torsion shaft. The nut socket has a recess for receiving a wheel nut to be tightened about a threaded bolt. A driver head is integrally fashioned with the other end of the torsion shaft and has a recess which is square in cross section for engaging the drive shaft of an impact wrench. Rotation indicia are fashioned on an exterior portion of the nut socket to permit an operator who is tightening a wheel nut to facilely visually determine when the torsion shaft relieves the impact torque from the nut socket and when the nut socket stops turning, preventing overtightening of the wheel nut beyond design specification in the secondary market.
