ABSTRACT:
An electronic torque wrench for engaging a workpiece includes a wrench body having a first end and a second end. A wrench head is disposed on the first end of the wrench body and is configured to engage the workpiece. A grip handle is disposed on the second end of the wrench head. A user interface is carried by the wrench body and includes a housing, a digital display, and an input device for inputting a preset torque value. A torque sensing element is carried by the wrench head and is electrically connected to the display device. A detent extends outwardly from one of the wrench body, the wrench head, and the user interface and a plurality of recesses is formed in another of the wrench body, the wrench head, and the user interface, each of the recesses being configured to releasably receive the detent. The display device is rotatable relative to the wrench head so that the detent is received by one of the recesses for retaining the display device in a desired angular position with regard to the wrench head.
