How to Choose the Right Pneumatic Impact Wrench for Your Industrial Bolting Application？

Pneumatic Tools also known as impact guns, impact tools or simply pneumatic impact wrenches, are specialized fastening tools designed to deliver large amounts of torque to nuts or bolts. By utilizing an anvil and hammer-style mechanism, impact wrenches require minimal effort from the user.

Impact wrenches are popular in the following sectors: automotive, aerospace, heavy equipment maintenance, construction projects, vehicle service, and product assembly.

While the basic principles of impact wrenches remain the same across styles and manufacturers, there are differences in torque output, drive size, and the physical configuration of the tool. We recommend American Made Air Tools to our customers whenever economically feasible because of their proven quality and durability.

The Basics of Impact Wrenches

Impact wrenches transfer energy from a rotating mass accelerated by an electric motor into energy storage. The energy is then connected to the output shaft, where it is blasted through the tool anvil in rapid succession, creating massive amounts of torque.

Since the output shaft is designed as a free-moving hammer shaft, the user will not have any reaction during operation. However, it should be noted that an impact wrench is not meant for precise torque application and cannot be set to shut off at a specific torque once the desired tightening has been achieved.

However, impact wrenches are critical components of a wide variety of products, structures, and vehicle assemblies. On any given day, you'll experience the benefits of an impact wrench. Impact wrenches are responsible for heavy-duty bolting around the world, from the cars we drive to the giant power lines towering over highways.
