1 Inch Pneumatic Tools Manufacturers's Familiar with the mechanism
Impact wrenches, also known as impact drivers or impact guns, are designed to tighten or loosen bolts. It is commonly used in mechanical and industrial applications, such as when changing tires and disassembling wheels, or when performing maintenance on oil platforms. There are electric, battery-powered or pneumatic options to choose from, each with different advantages and challenges.

The working principle is relatively simple. The impact mechanism composed of anvil, impactor (hammer) and spring enables the wrench to be tightened and loosened as needed. The tool accumulates energy through one or more turns of the hammer cage. Once the hammer hits the output shaft (anvil), a tightening or loosening torque will be generated.
