An impact wrench also called a rattle gun, impactor, air gun or torque gun is a special type of tool designed to help the user in optimum torque output with minimum physical effort.
In an impact wrench, the torque output is generated by its process of energy storage and then in sudden deliverance to the output shaft.
In the impact wrench, the main source of energy is compressed air but electric or hydraulic power is also used to generate the output.
The recent popular trend in wrench impact is the cordless electric devices which are being used in plenty now.
Wherever there is the need for the high torque output, the impact wrench comes in place.
Be it major construction projects, product assembly, heavy equipment maintenance, or automotive repair, an impact wrench is needed.
You can get it in many convenient sizes. It comes in every standard socket wrench size.
The sizes start from the small 1/4” and you will get it up to the large 3.5” size. This is one of the most commonly used power tools that can be available in every mechanic’s shop.
The big names in the business that produces high-quality impact wrenches are Hitachi, DeWALT, and Black & Decker.
The method of operation in an impact wrench is the use of a rotating mass which is made to accelerate by the motor and to store the high power energy.
Then suddenly it is connected to the output shaft which results in creating a high torque impact.
It is designed in such a manner that after the delivered impact, the hammer is allowed to spin freely. It simply does not remain locked to move.
Now, let’s see some of the common uses of the impact wrench and how it is used to help in different industries.
The first inline will be the use of impact wrench in automobile repair.
The impact wrench is used to open or remove any parts of the car that are bolted to the body or the chassis. It helps in removing tires, mufflers any other parts.
It is designed to drill fasteners into hard materials. The impact wrench motion is used to drive the screws into the metals and at the same time drilling into the same.
It can drive bolts into the holes. It drills the holes into the concrete slabs and helps in adding a brace with a bolt in place.
The wrench is applied to ensure that the bolt remains tightly even if a good amount of force is applied.
It also helps in removing the nuts and bolts in construction works. Sometimes environmental exposure causes rust to the nuts and bolts yet the wrench helps in removing them.

If there is some separation between two objects, an impact wrench is used to tighten them.
These are used heavily in the large machinery works too. It is used in almost all types of large machinery industries.
