Adjustable Wrench is a tool which can be used to loosen or tighten a nut or bolt.

An adjustable spanner, shifting spanner, shifter, fit-all, crescent wrench or adjustable-angle head wrench (American English) is a tool which can be used to loosen or tighten a nut or bolt. It has a "jaw" (the part into which the nut or bolt goes) which is of adjustable size, which allows for different size nuts and bolts to be handled by the same spanner. Compare this to the ordinary spanner which has a fixed size.The movable jaw should be snugly adjusted to the nut or bolt head in order to prevent rounding.

In addition, it's important to ensure that the movable jaw is located on the side towards which the rotation is to be performed, so that the jaw that is of the same piece as the handle receives the majority of the force when torque is applied via the tool to the fitting or fastener. This reduces risk of deformation of the movable jaw or the adjusting mechanism. Using the tool on the wrong side, in a manner such that the non-moveable jaw does not receive the greater part of the manually applied force, increases backlash against the moveable parts. That may result in damage to the tool or in slippage-related damage to the fitting or fastener.

This type of wrench should not be used on a rounded off nut, as this can overload the movable jaw. Nor should such a wrench be used "end on" in cramped quarters (except perhaps when the nut is barely more than finger-tight), where a socket wrench is more appropriate.
