How To Adjust A Torque Wrench


A torque wrench is a tool used to apply a specific amount of force or torque to a fastener such as a nut or bolt. It is important to apply the correct amount of torque to ensure a secure and reliable connection. If the torque is too high, you may strip the fastener or cause damage to the part it is being connected to. If the torque is too low, the connection may become loose or come apart. To ensure the proper amount of torque is applied, it is important to adjust the torque wrench properly.

Adjusting a torque wrench is relatively simple and straightforward. Here are the steps to adjust a torque wrench:

  • Check the torque setting on the wrench. Most torque wrenches will have a scale or digital display that shows the current torque setting. Make sure the wrench is set to the desired torque.
  • If the torque setting needs to be adjusted, turn the adjustment knob on the wrench. Turn the knob clockwise to increase the torque setting, and counterclockwise to decrease the torque setting.
  • Once the desired torque setting is reached, check the torque setting on the wrench again to make sure it is correct.
  • Once the torque setting is correct, you are ready to begin fastening. Make sure the wrench is in the locked position, and then apply pressure to the fastener. When the desired torque is reached, the wrench will click or slip, indicating that the fastener has been tightened to the correct torque.

It is important to remember that the torque setting on the wrench is not always exact. It is important to use a torque wrench that is accurate to within +/- 4%. To ensure accuracy, it is important to periodically check the wrench for calibration and make any necessary adjustments.

Adjusting a torque wrench is an important skill for anyone who needs to apply a specific amount of torque to a fastener. By following the steps above, you can make sure that you are applying the correct amount of torque to your fasteners, ensuring a secure and reliable connection.
