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 wrenches 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.
