A mechanical torque wrench for engaging a workpiece, the torque wrench including a wrench body, a wrench head pivotably secured to the wrench body at a pivot joint and including a workpiece engaging portion and a bar extending therefrom, a hand grip, a set spring, a block disposed between a rear face of the bar and the set spring, an adjustment assembly for selecting a preset torque value, a resistive element producing a first output signal, a sensor producing a second output signal, and a processor for converting the first output signal into the preset torque value and converting the second output signal into an applied torque value. The application of a peak applied torque value to the workpiece causes the wrench head to pivot relative to the wrench body.
