How does an Impact Wrench Work? Impact Wrench Basics

You are probably asking yourself, “how does an impact wrench work?” I will try to answer this question with my many years’ experience working with this tool. The majority of people do not realize how versatile and handy the tool really is until they have done themselves and realize how much help it can be.

Impact Wrench Parts

Impact wrenches consist of two parts – a taper rod that has a head and a sleeve. The taper rod is usually made of steel or aluminum. The head of the socket wrench is called a sleeve. These things separate the stroke of the socket wrench arm from the rotation of the bit or sleeve.

The head is typically made of steel or cast iron. The sleeve is usually of nylon woven material or soft rubber. This combination allows the wrench to spin freely, yet remain relatively still when you are using it.

How does an Impact Wrench Work

It is actually very simple to explain. As you know from any high school science class, an impact wrench works by applying a force to the opposing forces, or poles, which are opposite each other. The wrench works by gripping the end of the nut or bolt tightly with the impact wrench head. With the force applied, the nut or bolt is forced to move in a forward direction.

Output Torque

Most impact wrenches output a certain amount of torque. They are usually between five and ten pounds per square inch.

If the wrench you have isn’t designed to handle a lot of torque, then you will notice that you can’t use it to its full potential. If you don’t want to waste all your hard work on a project, then you should focus on getting one that can handle as much torque as possible.

There are impact wrenches out there with a ten pound per square inch output torque, but most people aren’t going to need that much power in order to complete a job.

As long as the torque setting is high enough to get the job done, then you can pretty much forget about other power-driven features.

What do You Use an Impact Wrench for

For Detailed Word

Impact wrenches come in different types for different purposes. There are impact wrenches used for drilling holes, like a hole punch, and there are impact wrenches that are used to do detailed work on metals and alloys. One of the most efficient ways of using an impact wrench is by applying it to a piece of wood or metal and using the “snap” effect to drive the screw or bolt. To do this, you must have the right sized socket, the right size impact wrench bit, and appropriate force to drive the bit or bolt. You should have a good grasp of basic mechanics before attempting this technique.

High Torque

One of the things that make high-torque impact wrenches so useful is that they can withstand a lot of force. They are commonly used in construction work where a lot of force is required. The materials that they are often made out of, like stainless steel or aluminum, ensure that they have very high torque. Because of the high torque, they can handle a lot of force when doing hard work and drilling into hard metal.


An impact wrench is perfect for just about any job. You won’t need to get another tool to perform the same job you already have done. If you want to add another tool to your arsenal, you can easily transfer anvils, reciprocating saws, grinders, and drill presses. This means that you won’t need to purchase other tools just to get anvils for use on your impact wrenches.
