They are also very handy when working on farm equipment or large machinery, as they allow you to work under big and tall vehicles. But impact wrenches are not essential for all mechanics.

If you’re learning how to change oil or rotate a tire, you won’t need one. However, if you plan to become a master mechanic, you will want an impact wrench as a part of your tool kit.

How to Use an Impact Wrench?

 Always follow these simple rules, and you’ll have no problems:

  • Don’t under-tightening – stop when you feel “friction” but before the threads begin to round off.
  • Grip the handle firmly and evenly, with your hand at the very end of the grip, where the handle’s cap joins it. Your palm should be flat and face the fingerboard.
  • Keep your other hand on the lever, near the trigger.

6. Use only the highest quality oil or grease – Do not use oil or grease with a low flashpoint. If you are using oil or grease, ensure it is the proper type with your specific impact wrench. Do not use oil or grease made for automotive use; it might eat away at the steel parts of your impact wrench. Instead, use high-quality grease or oil such as Pennzoil 5W-40, Castrol 10-50, or similar.

7. Keep an adequate distance – Always keep at least 16 inches of space between you and the object you are working on. Use a measuring tape to make sure you stay clear.

8. Work in a well-ventilated area – Dust and debris from working with an impact wrench can be very hazardous to your health. Make sure you have quite enough ventilation so that the dust and debris from your work area don’t endanger you or others.

Impact wrenches are used to tighten fasteners with a lot of kinetic energy, whereas a torque wrench is used to very accurately apply just the right amount of force (tension) needed to turn a nut or bolt. Hence, if you need a proper torque wrench, you should get one specifically designed for this purpose.

What Size Impact Wrench Do You Need?

You will need a size ten impact wrench since it is the standard size for automotive work. However, any impact wrench will do, as long as it has a torque rating of 20 foot-pounds or more.
