Adjustable tools are a category of hand tools designed to perform a specific function across a range of sizes or settings. Their primary characteristic is their ability to be modified or changed to suit different applications, unlike fixed-size tools. This adaptability makes them versatile and often reduces the need for a large collection of specialized tools.

The most common examples include adjustable wrenches, also known as crescent wrenches, which feature a movable jaw that can be tightened or loosened to grip fasteners of various dimensions. Adjustable pliers offer similar functionality, allowing for grip size adjustments to accommodate different objects. Adjustable spanners, pipe wrenches, and even certain types of screwdrivers with interchangeable bits can also be classified as adjustable tools. The mechanism for adjustment typically involves a screw or a lever that allows for precise control over the tool's working dimension. This adjustability is achieved through a sliding component that moves relative to a fixed part. The benefit of using adjustable tools lies in their convenience, cost-effectiveness by replacing multiple single-purpose tools, and their utility in situations where the exact size of the fastener or object is unknown or variable. However, it is worth noting that in some high-precision or high-torque applications, fixed-size tools may offer superior strength and a more secure fit.
