Abstract: A mechanical torque wrench including a wrench body defining an elongated interior compartment and a wrench head including a bar extending therefrom being pivotally secured to a first end of the wrench body. A hand grip located on a second end of the wrench body, the hand grip being non-rotationally fixed to the second end of wrench body, and a set spring is disposed within the wrench body. A pawl is disposed between the bar and the set spring. Rotation of a dial screw in a first direction compresses the set spring and rotation in a second direction allows expansion of the set spring. A set ring is operatively connected to the dial screw and rotatable relative to the wrench body. A resistive element produces an output signal that depends on a position of the dial screw relative to the resistive element. A processor converts the output signal into an equivalent torque value in a selected system of units for display on a user interface.
