The 1/2 impact wrench is the most common size. They can be purchased in many varieties with varying power levels. Some are made for general use, while others are designed for heavy-duty jobs. Each impact wrench comes with a different set of attachments, including chucks and bits that can be used to tighten and loosen screws.

Impact wrenches provide high torque with minimal effort. They produce their torque by storing energy in rotating masses, which is suddenly delivered to the output shaft. They are typically powered by compressed air, but battery-operated cordless versions are also available. These tools are used to tighten bolts, screws, and other fasteners.
