How Much Torque Does an Impact Wrench Have?

Last Updated:

The impact wrench is used to lose or tighten the lug nuts due to its high torque production and impact rate. There are dozen of impact wrenches available in the market. But its impact rate and torque are varied with the brand. When you buy an impact wrench, you must know how much torque does an impact wrench have?

Normally, impact wrenches have 500Nm-600Nm torque, which is sufficient for general purposes. But for the heavy-duty tasks, we can use a Makita impact wrench with a maximum of 2,050 Nm nut-busting torque and 1,800 Nm fastening torque which is a special design for heavy-duty works.

Normally impact wrenches are mostly used in domestic or DIYs. Hence it will not need high torque impact wrenches. The mid-range impact wrench is really useful for these projects. So let’s see what the torque that each impact wrench have and more detail about the torque is? Keep reading on!

What is the Torque of the Impact Wrench?

The torque in an impact wrench is the force that the wrench uses to rotate an object around an axis or pivot point. It is typically measured in Newton meters (Nm) or foot-pounds (ft-lb). A general-use impact wrench has 500Nm-600Nm torque. You can use 1500Nm – 2500Nm impact wrenches for the heavy-duty lug nut tasks.

Impact wrench has a specific mechanism for torque generation. It is called an epicyclic gear system. There is a sun and planetary gears. When the sun gear is rotated, planet geares also rotate at a different speed. As a result of this, torque has increased more than impact drivers. There is no high noise. Some impact wrenches combine these two mechanisms in order to have the best user experience.

For light vehicles and DIY, you can use an electric, cordless, brushless impact wrench with a suitable tool head and torque.

How Much Torque Do Lugnuts Need?

Impact wrenches are used to tighten or lose the lug nuts. In order to properly tighten the impact wrench should have sufficient torque for the tightening. Below is the typical torque range for the lug nuts.

Why Is an Impact Wrench Torque Reduced?

An impact wrench torque is reduced due to these 5 reasons such as,

  1. Wear and tear in the tool – The internal components, such as gears, bearings, and other parts, can wear down over time. This causes a decrease in performance.
  2. Lack of lubrication in the impact wrench – If the impact wrench is not properly lubricated, it can cause friction and heat, which can reduce the torque. Prolonged lack of lubricating cause to overheating the impact wrench as well.
  3. Poor quality impact wrench – Not all impact wrenches are created equal. Some are simply made with inferior parts or poor craftsmanship, which can lead to reduced torque.
  4. Damaged or dirty components – If the components of the wrench are damaged or dirty, it can affect the performance of the wrench. Regular cleaning and inspection can help to prevent this.

Hi, I am Tom Mackency. It has been 10 years that I have been working as a professional woodworker since 2013. I am really enjoying my carrier by creating many kinds of projects in my workshop. But mostly I like for home improvement projects. Home improvement and DIY projects are the most interesting things for me. More than that, the coolest things are power tools. Those are very precious and efficient than a decade ago. So I try to introduce so many things about power tools, woodworking, DIY projects, home improvement and many more interesting topics here.
