Torque Limiting Extension Bars

Start with 20% lower

Select a torque sticks rated for approx 20% lower of the final torque specified. Use an air impact wrench to tighten the lug nuts. When the torque limit is reached, it flexes and stops.

Final Procedure

The last and most important step is to finish off with a torque wrench. Set the torque wrench with the specific torque and finish off until you can hear a click from the torque wrench
