An air wrench, also known as a pneumatic wrench, is a powerful tool that uses compressed air to tighten or loosen bolts and nuts. It is commonly used in automotive repair and construction because it can deliver high torque with minimal effort. This makes tasks like changing tires or assembling machinery much faster and easier compared to manual tools. These tools come in various sizes and styles, including impact wrenches and ratchet wrenches, each designed for specific applications. Air wrenches are typically connected to an air compressor, which provides the necessary power. Their efficiency and speed make them a favorite among mechanics and construction workers.
