How to Use the Correct Amount of Torque

It is vital to always consider the right amount of torque for ensuring that it actually works.

We have already mentioned a chart above for you to consider above. Such a chart helps you to see how much torque to use for loosening lug nuts.

The safest amount you can start with is using 80 to 100-foot pounds. Make sure you start slow with the torque and increase the torque when necessary.

You should also not apply unnecessary torque when you have already tightened the lug nuts. The same applies when loosening as too much torque can easily break the lug nuts.

Ensure that you are also not stressing the lug nuts so much. This is especially when the nuts are rusted or older. You may have to add a penetrant to ensure that the lug nuts can become loose with ease.

Snapping off the lug nuts can make it tough to remove the lug nuts. That is why we still recommend applying gradual torque to the lug nuts.

Electric Impact Wrench for Removing Lug Nuts

An electric impact wrench can also be used for removing lug nuts. What is important is that you should always use a high rating for an impact wrench.

The higher rating for an electric impact wrench will make it easier to get the job done.
