Abstract: A torque signaling attachment for a conventional torque wrench for producing a visual or audible signal when the wrench is applying a predetermined torque. In a conventional torque wrench, the angular offset between the torque beam and the indicating pointer is proportional to the applied torque. The signaling attachment detects a predetermined lateral offset between the beam and pointer. The indicating device is secured to the torque beam, and the torque corresponding to the predetermined lateral offset is determined by the location of the signaling attachment on the beam. When the beam becomes laterally offset from the pointer by the predetermined amount, the pointer contacts the signaling device to complete an electrical circuit and produce a torque indicating signal. The signaling device is calibrated by applying a predetermined torque with the wrench and adjusting the position of the device along the torque beam until the signal occurs.
