A ratchet wrench is a versatile hand tool designed to tighten or loosen nuts and bolts with ease and efficiency. It features a ratcheting mechanism that allows continuous motion in one direction while preventing movement in the opposite direction. This mechanism eliminates the need to remove and reposition the wrench after each turn, saving time and effort. The wrench typically has a handle connected to a gear-and-pawl system inside the head. By flipping a switch or lever, users can change the direction of rotation. Most ratchet wrenches are compatible with interchangeable sockets of various sizes. This makes them suitable for a wide range of mechanical and automotive tasks. They come in different drive sizes such as 1/4-inch, 3/8-inch, and 1/2-inch to suit different torque requirements. Ratchet wrenches offer improved grip, leverage, and speed compared to traditional wrenches. Their compact design also allows access to tight or confined spaces.
