Correcting torque wrench calibrations 1 adjust the torque wrench using the weight. A torque wrench, as the name suggests, is a wrench used to apply a specific torque to a fastener such as a bolt or a nut. Turn the cone to set the calibration as follows: The operator then stops applying torque and the desired value on the torque tool is compared with the value displayed on the torque wrench tester. The simple answer is anywhere from $25 to $200.. I'll show you how by just using a scale, measuring tape, a. The amount of torque that is applied depends on the mount of force that you apply to the tool's handle and the length of the wrench. You can do this by using a screwdriver or a similar tool to complete the process.
