ABSTRACT:
A torque wrench is provided with a unique interconnection between the hinge, pivot and plunger. Both the hinge and plunger are channeled entirely across the width of their interfaces with the pivot normal to the plane of application of torque. A pivot retainer is provided to laterally constrain movement of the pivot. The pivot retainer may take the form of a flat disk with a rectangular aperture centrally located therein, it may be embodied in restraining pins extending transversely across the channel in the plunger face or it may include an axial guide rod extending through the plunger to engage and restrain the pivot.
