How to Use air torque wrench?

Mar 17, 2023
Air impact wrenches are tools that you'll see in a mechanic's shop or a tire store. These tools deliver immense torque when you need them most - for instance, to loosen or tighten lug nuts on a car.
The air pressure used by an air impact wrench is usually much higher than the air pressure of a standard hand-held wrench, and that's why you'll hear a whirring sound when you're using one. These wrenches are a handy tool to have around your home or garage, but it's important to know how to use them safely and effectively so you can get the most from them.
Torque and impact wrenches
The amount of torque you can apply to a bolt or nut depends on how tightly the nut or bolt is wound into place and how stripped the threading on the nut or bolt is. The right amount of torque will mean that the nut or bolt can be turned without the risk of breaking or damaging it, but too much can be dangerous.
The best way to use an air torque wrench is to follow the manufacturer's instructions and the torque ratings or specifications of the nut or bolt. This way, you can avoid over-tightening or under-tightening it, which could damage the nut or bolt and cause unnecessary wear and tear.
