Ratchet Ring Spanner

A ratchet ring spanner, also known simply as a ratchet ring or ratcheting wrench, is a type of hand tool designed for tightening or loosening fasteners, such as nuts and bolts. It features a ring-shaped end with gear teeth, allowing it to engage with the corresponding gear teeth on the fastener. The ratcheting mechanism enables the user to turn the tool in one direction while maintaining contact with the fastener, eliminating the need to lift and reposition the tool for each turn. This design enhances efficiency and convenience, particularly in tight or confined spaces where a traditional wrench may be difficult to use.
