How to Read the Torque Value on a Torque Wrench?

[TessaDella]

There is a window on the handle of the torque wrench, which contains a scale displaying the torque value. Below is relevant information: 1. Adjustable Preset: Torque wrenches are divided into fixed-value and preset types. An adjustable preset torque wrench allows the preload torque value to be adjusted as needed by the user. Before using the wrench, the actual tightening torque must be preset on the wrench. When tightening threaded fasteners, if the actual torque equals the preset torque, the wrench will emit an alarm sound, at which point the wrench should be stopped. After releasing the wrench, it will automatically reset to the preset torque value. 2. Method for Setting the Preload Torque Value: Observe the torque value on the wrench. There is a window on the handle, and the scale inside will indicate the specific torque value. To set the preload torque value, first loosen the tail cap at the end of the wrench, then rotate the handwheel at the end. When using a torque wrench, it is generally important to check before use—ensure the assembled parts meet the required values and inspect for any missing components.
