What is generally the primary use of an adjustable wrench?

The primary use of an adjustable wrench is to grip objects of varying sizes. This tool is specifically designed with a movable jaw that allows the user to adjust its width, enabling it to accommodate different sizes of nuts, bolts, and other fasteners. This versatility makes it a valuable tool in mechanical and automotive applications, where components may not always be of a standard size.

The adjustable feature stands out in applications where a fixed-size tool would be inadequate. As a result, this type of wrench is often preferred for tasks that involve various threaded fasteners, allowing for efficient and effective work without needing a complete set of wrenches in different sizes. This practical design helps streamline tasks and improve productivity.
