How much Torque do you need in an Impact Wrench?
The amount of torque you need from an impact wrench depends entirely on your intended application.
The first thing we must take into consideration is the size of the bolts you will be removing. Why, because larger bolts can take higher amounts of applied torque without stripping. It is common for mechanics to apply too much torque to an application thinking more is better, it isn’t! E.g. putting 500ft lbs of torque into a bolt that only needs 100ft lbs.
If too much torque is applied you run the risk of over-tightening a bolt which can lead to stripping and stretching of the threads, potentially causing it to break or crack. On the other hand, apply too little torque and you increase the likelihood of the bolt vibrating loose and falling out.
Remember, with an impact wrench the user has no sense of how much torque is being applied or how tight the bolt is. This is why it is so important to use the correct impact wrench with suitable torque for the application.
Let’s get to the numbers. Most people will be fine with a low to mid-range 3/8’’ or ½’’ cordless impact wrench in the range of 300 – 500ft lbs. This should suffice for the majority of automotive and industrial applications. For the few working on heavy-duty equipment beyond your standard truck or car, aim for a ½’’ cordless impact wrench capable of producing torque in the 750 – 100ft lbs range.
Will a Cordless Impact Wrench Remove Lug Nuts?
A general rule of thumb for removing a lug nut is that you’ll need about 100 ft. lbs of torque. We know this because it takes around that much torque to put it in place.
However, it isn’t always that straight forward. Most lug nuts tend to be in position for a long time before they need to be removed. During this time, they come under the effect of several factors, each changing the amount of torque needed to remove it.
For example; lug nuts can accumulate rust, especially if they have been regularly exposed to water. It may have become stuck or frozen due to environmental conditions or maybe it has a broken thread due to over-tightening when it last underwent maintenance.
As you’d expect these factors will increase the amount of torque required to remove it. Just how much isn’t an exact science. Under perfect conditions 100ft lbs of torque should remove a lug nut, assuming it was tightened correctly in the first place, but chances are you’ll need a lot more.
If you are buying an impact wrench primarily to remove lug nuts, be safe and go with one that can generate plenty more than 100ft lbs. I would suggest 350ft lbs as a bare minimum.
Tip: If your current impact wrench isn’t quite doing the job, try using a breaker bar to loosen the lug nut then use your impact wrench to spin it completely off.
Wrapping it up
After many hours of extensive industry-specific research, we are confident to present what we believe to be the 7 best cordless impact wrenches on the market. In our eyes, a good cordless impact wrench must be reliable, offer comprehensive control over its output of torque and have a build quality that will stand up to years of repeated use.
It is for these reasons our best pick goes to the Makita XWT08Z. Built with the most durable materials that house a piece of machinery that will take on any job you throw at it. It is certainly more of an investment than a standard purchase!
