ABSTRACT:
A torque applying and indicating wrench is comprised of a pawl with a torque sensing end for both ratcheting, and direct sensing of torque during application. The torque sensing end is bifurcated into a cantilevered flexing beam and an optional reference beam. The flexing beam engages one or more ratchet teeth from a ratchet wheel contained in the wrench head of an elongated tool body. Torque is then transduced and indicated either mechanically or electronically.
