A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning. In Commonwealth English, spanner is the standard term. The most common shapes are called open-ended spanner and ring spanner.
