Abstract: An electronic torque wrench is disclosed that instantaneously logs data in real time from a torqueing operation and can later transfer the data to an external device, such as a computer, for further analysis. For example, the computer can create a graph that can be analyzed to determine relevant parameters of the torqueing profile. The parameters of the graph can be analyzed to determine whether the torqueing operation was performed properly for a particular work piece or job task, or to assist users in future torqueing operations.

Abstract: A method for improving wear properties of a torque wrench includes electroplating one or more components of the torque wrench with zinc. In an aspect, one or more of an interior surface of a tube component, a surface of a secondary arm, a surface of a cam, and a surface of a pawl components may be electroplated with zinc. These components may interact to provide a click mechanism. For example, the pawl component may be seated between the secondary arm and the cam components, and the cam is adapted to move against a bias force when the secondary arm shifts the pawl in response to a preset torque level being achieved. The electroplated zinc layer provides a corrosion-resistant, softer and smoother surface for these components, and serves as a frictional reducer when the zinc oxidizes to form zinc oxide, which improves the accuracy life of the tool.
