A spanner, in English terminology, is a type of wrench used for turning bolts and nuts. It comes in various shapes and sizes to fit specific bolt heads or nut threads, providing leverage to loosen or tighten them securely.

They can be manual or powered, with the latter being electrically or pneumatically operated for increased efficiency.
