Adjustable wrenches, also known as crescent wrenches or shifting spanners, are versatile hand tools used for gripping and turning nuts, bolts, and other fasteners of various sizes. They are designed with an adjustable jaw that can be opened or closed to fit different sizes of fasteners. The jaws are typically serrated to provide a better grip on the fastener, and the wrench can be adjusted by turning a screw or knob located near the head of the tool. Adjustable wrenches come in a variety of sizes, with the larger ones being able to handle fasteners up to several inches in diameter. They are commonly made from steel or other durable metals, and may have a chrome or other corrosion-resistant finish. Some models may also have a rubber or plastic handle for improved grip and comfort. One advantage of adjustable wrenches is their versatility. With a single tool, a user can handle a wide range of fastener sizes, reducing the need for multiple wrenches. However, they may not provide as secure a grip as a wrench specifically designed for a particular size of fastener, and may be more likely to slip or round off the corners of the fastener. Overall, adjustable wrenches are a useful addition to any toolbox or workshop, providing a convenient and versatile tool for a variety of tasks.
