How to calibrate your impact wrench for torque sticks

A torque stick can’t work properly if you don’t first calibrate each stick to your impact wrench. Here’s how to calibrate your impact wrench for torque sticks.

Set your impact to its lowest torque setting.

Insert the torque stick and tighten the lug nut until the nut stop turning.

Using a hand held torque wrench set to the carmakers’ recommended final torque, try tightening the lug nut with the torque wrench. If the handheld torque wrench immediately clicks without any additional turning motion, the lug nut is over -tightened. To adjust your impact, reduce air pressure. Repeat the calibration until the lug nut turns slightly when tightened with the handheld torque wrench.

You must repeat this calibration for each torque stick, adjusting air pressure to the impact each time to prevent over tightening.

To use the torque sticks after calibration, you must adjust the impact wrench to the corresponding setting and air pressure for each torque stick or the torque will be wrong.
