ABSTRACT:
This disclosure relates to a tool for rotating elements, such as nuts, bolts, screws or like fasteners, and includes a ring having ratchet teeth, the ring being driven by a lever, a pawl carried by the lever for engaging the ratchet teeth, a flexible tension-applying member in at least partial surrounding relationship to the ring, means for supporting the pawl, and the tension-applying member being disposed between the supporting means and the lever whereby upon movement of the lever in a first direction the pawl rotates the ring through the engagement of a tooth of the ring and the tension-applying member deforms slightly to frictionally grip the ring.
