What is a "ratchet wrench"?

A ratchet wrench is a type of wrench that allows continuous turning in one direction without needing to lift and reposition the tool. It features a mechanism inside that enables the wrench to click or as it turns, so the handle can be moved back without losing grip on the fastener. This makes it useful for tightening or loosening nuts and bolts in tight spaces where movement is limited. Ratchet wrenches are commonly used in automotive, mechanical, and general repair work for their convenience and efficiency.
