A tool known as a wrench or spanner is employed to provide grip and mechanical leverage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or prevent them from turning. In Commonwealth English, the term spanner is commonly used. The most prevalent shapes are referred to as open-ended spanners and ring spanners. Typically, the term wrench is utilized for tools that manipulate non-fastening devices (e.g., tap wrenches and pipe wrenches), or may be employed for a monkey wrench—an adjustable pipe wrench. In North American English, the standard term is wrench. The most common shapes are known as open-end wrenches and box-end wrenches. In American commerce, such a wrench may be referred to as a spanner wrench to differentiate it from the British sense of spanner. Higher-quality wrenches are typically manufactured from chromium-vanadium alloy tool steels and often drop-forged. They frequently have chrome plating to resist corrosion and for ease of cleaning. Hinged tools, such as pliers or tongs, are not generally classified as wrenches in English, but exceptions include plumber wrenches (pipe wrenches in British English) and Mole wrenches (sometimes referred to as Mole grips in British English). The term can also be used colloquially to describe an unexpected obstacle, for example, "He threw a spanner into our plans" (in U.S. English, "monkey wrench").
