An Air Ratchet Wrench is a pneumatically powered hand tool designed to tighten or loosen nuts and bolts quickly and efficiently, especially in automotive repair, machinery maintenance, and assembly applications.It combines the mechanical ratcheting function of a manual wrench with the speed and torque of a pneumatic motor, allowing the operator to perform repetitive fastening tasks with minimal effort. The tool operates by using compressed air to drive an internal rotary vane motor, which turns a square-drive ratcheting head — providing smooth, continuous motion until torque resistance stops the rotation.
