If you are a new user, this step-by-step guide is for you.
How to Use Impact Wrench – Preparation
Impact wrench has many uses. Here is a detailed guide on how to use impact wrench. Please follow all the instructions properly:
Check the Battery or Power Supply
When preparing to use your impact wrench, you first want to check the battery or power supply. It will ensure you have enough juice to complete the job without the tool dying. If you’re using a cordless impact wrench, check the battery level, and if necessary, make sure to charge it fully. If using a corded impact wrench, ensure the power cord is plugged in and working.
You don’t want to start a job only to realize halfway through that the battery is dead or the power cord has come unplugged. Trust me. It’s a frustrating experience! So take a moment to check the battery or power supply before you get started, and save yourself the hassle later on.

Select the Right Socket
The next step in preparing to use your impact wrench is to select the correct socket. It is crucial, as using the wrong socket size can damage both the tool and the bolt or nut you’re working on.
By measuring the bolt or nut, you need to loosen or tighten it. You’ll want to ensure the correct socket size for the job. If you’re unsure what size socket you need, consult your impact wrench’s manual or research online to find the right size.
Here are some examples of when to select the correct socket for your impact wrench:
- Changing the tires on your car – you’ll need a socket that fits the lugs on your wheels.
- Installing furniture – you’ll need a socket that fits the bolts for attaching legs or brackets to a table or chair.
- Replacing an appliance – you’ll need a socket that fits the bolts holding the appliance in place.
- Building a deck – you’ll need a socket that fits the bolts for attaching the decking to the frame.
- Working on machinery – you’ll need a socket that fits the bolts for removing or tightening parts.
Determine the torque specification.
Determining the torque specification is an essential step in using an impact wrench. The torque specification is the amount of force needed to tighten or loosen a bolt or nut. If you use too much power, you can damage the bolt or nut, while using too little force may result in the bolt or nut coming loose. If you are using it for cars, here is how you can determine the torq specifications:
- Consult the owner’s manual: The first place to look for the torque specification is in the car’s manual. The manual should specify the recommended torque for the lug nuts or bolts on the wheels.
- Check online: If you don’t have the owner’s manual, you can search online for the torque specification for your specific car model. This information can often be found on car forums or automotive repair manuals.
- Contact a professional: If you still need clarification, contact a professional mechanic or tire shop. They can tell you the correct torque specification for your car.
How to use Impact Wrench – The Main Part
Position the Socket on the Bolt/Nut
Make sure the socket is securely fastened to the bolt or nut, as you don’t want it to come off while in use. Then, line up the impact wrench with the socket, ensuring it’s properly engaged.
At this point, you’re ready to start using the impact wrench. Follow the manufacturer’s instructions for the tool and pay attention to the torque settings to ensure you’re using the correct force.
Remember to work slowly and carefully, as over-tightening or over-loosening a bolt or nut can cause damage to the item you’re working on or the tool itself. Take your time and be patient, and you’ll be able to complete the job quickly.
Squeeze the Trigger to Engage the Tool
As you squeeze the trigger, the impact wrench will start to turn the bolt or nut. You’ll feel the force of the tool as it does so, and you’ll be able to hear the sound of the motor. Depending on the torque specification, you may need to squeeze the trigger for a longer or shorter amount of time.
It’s essential to keep your grip steady and secure as you use the impact wrench. Keep your other hand free and clear of the tool to avoid injury. If you’re tightening a bolt or nut, be careful not to over-tighten it, as this can cause damage to the item you’re working on or the tool itself.
Apply pressure until the bolt/nut is loosened or tightened
Once you’ve engaged the tool, keep squeezing the trigger and applying pressure until the bolt or nut is loosened or tightened to the desired level. Pay attention to the torque setting to ensure you use the correct force. Stop applying pressure once the bolt or nut is entirely loosened or tightened.
Release the trigger to stop the tool
When the bolt or nut has reached the desired level of tightness, release the trigger to stop the tool. Disconnect the socket from the bolt or nut and inspect the results. Repeat the process as needed until the job is complete. Always remember to follow safety guidelines when using power tools.
