What Is Spanner?
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.
Higher quality spanners are typically made from chromium-vanadium alloy tool steels and are often drop-forged. They are frequently chrome-plated to resist corrosion and for ease of cleaning.
Hinged tools, such as pliers or tongs, are not generally considered wrenches in English, but exceptions are the plumber Spanners (pipe wrench in British English) and Mole Spanners (sometimes Mole grips in British English).
The word can also be used in slang to describe an unexpected obstacle, for example, “He threw a spanner in the works”
