A spanner is a tool that is used to grip and turn nuts and bolts. It looks like a metal rod with two metal jaws that can be adjusted to fit different sizes of nuts and bolts. Spanners are often used by mechanics and engineers to tighten or loosen bolts in machines and equipment. In everyday life, you might use a spanner to tighten a loose bolt on a bike or to assemble flat-pack furniture.
