For loosening and tightening bolts, an impact driver is necessary. The question is, how much torque does it need?
There is no direct answer to this question as the amount of torque needed is determined by the task. Applying too much or too little torque will not produce the desired effect. I have often researched “how much torque do I need in an impact driver,” and today I will share my knowledge with you.
How Much Torque Is Needed In An Impact Driver?
As I have mentioned already, the amount of torque needed on an impact driver is mainly determined by the task you are performing. For example, when you are attempting to take lug nuts out from car tires, you will need to put around 350 ft.-lbs. of torque.
On the other hand, when you are working on large projects like yard construction, you might need torque as high as 700 ft.-lbs.
There is no standard range that you can set for every task. You need to understand the nature of the work and set the torque on the impact driver accordingly.
How To Adjust Torque On Impact Driver?
Adjusting the torque level according to your requirements can help you get the desired effect on the impact driver. It is quite understandable that to tighten a larger bolt, you would need to apply more torque compared to what a smaller bolt would need.
Modifying the torque is not too much of a task when it comes to modern impact drivers. If you are using an electric or cordless impact driver, adjusting the torque is as simple as setting the dial.
On the other hand, when working with pneumatic wrenches, your options are a bit limited, and you have to put some effort into modifying the rotational force.
What Happens In Case There Is Excess Torque?
Bear in mind, over-torqueing does not always mean that you will be able to get better and faster work. In reality, too much torque can lead to the breakage and cracking of bolts. Sometimes when lug nuts get over-torqued, they might lead to the brake rotors breaking or the hub flange getting damaged.
If you end up doing uneven tightening, the rotor can get balanced off the center, and that might result in warping.
Final Words
That’s all I have for you today!
I hope that after reading this guide, you will better know when to apply how much torque on your impact driver. It is best that you get a driver that comes with adjustable settings so that you do not have to use a different one for every purpose.
Increasing the torque on some impact drivers may be more difficult than others. So, you need to check that before making a purchase. And do not forget to keep a watch on this space for more exciting reads.
Until next time, adios!
