Abstract
A wrench for selectively turning a either conventional polygonal nut or a locknut having a key-receiving configuration onto a threaded stud including a wrench body, a polygonal bore in the wrench body, a rectilinearly slidable bit in the bore and biased to an outwardly extending position by a spring, a nose on the bit for mating engagement with the key-receiving configuration of the locknut, a first shoulder within a counterbore of the wrench body for engaging an end of the locknut, the bit being retractable against the bias of the spring when the polygonal nut is inserted into the polygonal bore for mating engagement therewith, and a second shoulder on the wrench body for engaging a shoulder on the polygonal nut. A wrench for turning a polygonal nut having a bore therein including a plunger having a tip thereon for entering the bore in stable supporting relationship, a spring for holding a polygonal nut in encircling relationship and an internal configuration in the wrench for turning the polygonal nut. A wrench for turning a locknut having a bore therein including a plunger having a tip thereon for entering the bore in stable supporting relationship, a bit slidable in the bore for holding a locknut in turning relationship, an internal surface in the bit for releasably holding the locknut, and an internal configuration in the wrench for turning the bit.
