An adjustable spanner, also known as an adjustable wrench, is a versatile hand tool used for tightening or loosening nuts and bolts of varying sizes. It is designed with an adjustable jaw that can be moved up or down the tool's shaft to fit different sizes of nuts or bolts. The jaw is typically serrated to provide a better grip on the fastener, preventing slippage and damage to the nut or bolt. The tool's handle is usually made of metal or plastic and is designed to provide a comfortable grip for the user. Adjustable spanners are commonly used in a variety of applications, including plumbing, automotive repair, and construction. They are particularly useful in situations where a range of nut or bolt sizes are present, as they eliminate the need to carry multiple wrenches of different sizes. Additionally, they are often used in tight spaces where a traditional wrench may not fit. One of the key advantages of adjustable spanners is their versatility. They can be used to tighten or loosen a wide range of fasteners, making them a valuable addition to any toolbox. However, it is important to use the correct size of spanner for the job, as using an incorrectly sized spanner can damage the fastener or the tool itself. In summary, adjustable spanners are a versatile hand tool used for tightening or loosening nuts and bolts of varying sizes. They are designed with an adjustable jaw that can be moved up or down the tool's shaft to fit different sizes of nuts or bolts, making them a valuable addition to any toolbox.
