An air impact wrench is a wonderful tool to tighten or loosen bolts and nuts. If you know how to use a cordless impact wrench properly, you can enhance its longevity, get the most out of its performance, and finish the task in no time. However, if you’re not well-acquainted with the tool, you may make mistakes that can turn into severe injuries or accidents.
That’s why Tools Warehouse brings this in-depth guide where we detail the common mistakes you might be making. We are also offering solutions and prevention tips that will help you use an impact wrench correctly.
Avoid these Mistakes When Using an Impact Wrench
What is an impact wrench used for? -- If you know it, you won’t make the following mistakes. But if you do, we have detailed the solutions as well:
Mistake 1: Incorrect Torque Settings
Too much or too little of anything is bad, and the same goes for torque settings. If your torque pressure is too heavy, it can damage fasteners, strip threads, and crack the material. However, less torque can cause loose bolts, which will affect the structural integrity of the project.
|
Avoidance Tips/ Solutions |
|
- Make sure you know the torque specifications of your project before you kickstart it. - Maintain your impact wrench for consistent torque delivery. - You can ensure proper tightening using a torque stick or torque wrench. It can give precise settings, especially for engine work or wheel lugs. |
Mistake 2: Not Maintaining/ Storing the Tool Correctly
You must maintain your power tool regularly so it can function without issues. There will be reduced performance, more wear and tear, expensive repairs, and even replacements if you neglect it. Also, if you store this tool in damp or dirty places, you’ll see rust and deterioration over time.
|
Avoidance Tips/ Solutions |
|
- Keep cleaning the tool regularly after use so there’s no dirt, debris, or dust. - You need to keep your impact wrench lubricated with air tool oil to keep things running smoothly. - Make sure to check and replace parts that have been worn out, like O-sockets or impact rings, that can lead to malfunctions. - Avoid moisture buildup by draining the air compressor regularly, which can damage the tool’s components. - Keep the impact wrench in a cool, clean, and dry place. - If you can, keep the air impact wrench in a protective case, away from moisture and dust. |
Mistake 3: Improper Air Pressure
If you know how to use an impact wrench, you know that it uses compressed air to generate power and high-torque delivery. If the air pressure here is not proper, it will lead to inefficient performance and may even damage the tool.
If you use the tool at extremely low pressure, it can affect the tool’s effectiveness. Excessive pressure, on the other hand, will strain internal components and shorten the lifespan of the tool.
|
Avoidance Tips/ Solutions |
|
- Make sure the impact wrench uses are delivered using a properly regulated air compressor, so there’s consistent pressure. - The recommended impact wrench air pressure is 90 and 120 PSI. - Regular inspection of connectors and hoses is necessary to detect leaks that can reduce air pressure. |

Mistake 4: Not Draining the Air Compressor
Compressed air of an air impact wrench holds moisture. It can accumulate in the air compressor tank and cause rusting. This can damage the air and the wrench’s quality.
|
Avoidance Tips/ Solutions |
|
- Drain the air compressor tank daily or after each use to remove accumulated moisture. - You can use an air dryer or water separator to reduce moisture content before it reaches the tool. |
Mistake 5: Ignoring Air Hose Size and Length
If the air hose is too long or has a smaller diameter than necessary, the airflow will get restricted. The power output, as a result, would be reduced.
|
Avoidance Tips/ Solutions |
|
- The air hose you use should match the recommendations given by the manufacturer. - Most impact wrenches are compatible with a ⅜-inch hose. - For a high-power model, you can use a ½-inch hose. - Optimal airflow is possible only if you use a hose length that is short. |
Mistake 6: Using the Wrong Socket Type
Standard sockets are not designed to withstand the high torque produced by an air impact wrench. If you use regular sockets, they can cause the wrench to crack or shatter, leading to injury.
|
Avoidance Tips/ Solutions |
|
- You should always use impact-rated sockets, which are made of stronger materials and can absorb the high-impact force of the tool. - Sockets should have the label “impact-rated” or can be made from chrome-molybdenum steel (Cr-Mo). |
Mistake 7: Holding the Trigger for Too Long
Holding the trigger for an extended period without achieving movement can overheat the tool. It can cause excessive wear on the hammer mechanism.
|
Avoidance Tips/ Solutions |
|
- If a fastener does not loosen within a few seconds, stop and reassess. - Now, try using a penetrating lubricant such as WD-40 or PB Blaster. - Or you can use a breaker bar to loosen the fastener before switching back to the impact wrench. |
