A digital torque wrench is disclosed having a transducer beam with a reduced thickness web therein. At least one strain gauge sensor is mounted to the internal web to measure the shearing stress within the web as the wrench is rotated. By using such a reduced thickness web, mounting the sensors in opposed orientations, mounting the transducer beam to the torque wrench handle using first and second longitudinal flanking pins, and providing the transducer beam in a tapered shape, the resulting measurement of the torque wrench is very accurate. Moreover, a rotational interface module with digital display is provided to facilitate reading of the display by the user.
