A wrench and a ratchet are both tools used for tightening or loosening fasteners, but they differ in design and functionality. A wrench, also known as a spanner, is a hand tool with a fixed or adjustable opening at one or both ends. It is used to grip and turn nuts, bolts, or other fasteners. Wrenches come in various types, such as open-end, box-end, combination, and adjustable wrenches. They require the user to reposition the tool on the fastener after each turn, which can be time-consuming and cumbersome in tight spaces. A ratchet, on the other hand, is a type of wrench that incorporates a ratcheting mechanism. It typically consists of a handle and a socket that fits over the fastener. The ratcheting mechanism allows the user to turn the fastener in one direction without removing the tool from the fastener, making it more efficient for repetitive tasks. The ratchet handle can be moved back and forth, engaging the mechanism to turn the fastener incrementally. This feature is particularly useful in confined spaces where a full rotation of a traditional wrench is not possible. In summary, the primary difference lies in their operation: a wrench requires repositioning after each turn, while a ratchet allows continuous turning without removal. This makes ratchets more efficient for certain tasks, especially in tight or awkward spaces.
