Torque wrench calibration is the process of adjusting a torque wrench to ensure that it is accurately measuring and applying torque. This is important because using an inaccurate torque wrench can lead to over- or under-tightening of fasteners, which can cause serious problems. For example, over-tightening a bolt can strip the threads or damage the bolt head, while under-tightening a bolt can cause it to come loose and fail.
There are several different methods for calibrating a torque wrench. The most common method is to use a torque wrench calibration machine. These machines apply a known amount of torque to the wrench and measure the wrench’s output torque. The wrench is then adjusted until its output torque matches the known torque.
