An electronically indicating torque wrench utilizes a variable frequency stress transducer to detect the level of torque applied by the wrench. The stress transducer is operatively coupled to an arm of the wrench, said arm having a mechanical stress that is a function of an applied torquing force. The output of the stress transducer is compared to a reference whose calibration corresponds to desired torque settings. An indicator provides audible and visual indications when the applied torque equals the desired value.
