Which tool is specifically designed to turn or hold a nut or bolt with a hexagonal head?

A wrench is designed to grip and turn nuts, bolts, and other fasteners with hexagonal (six-sided) heads. Common types include the open-end wrench, box-end wrench, combination wrench, adjustable (crescent) wrench, and socket wrench. A chisel cuts material, a file smooths or shapes surfaces, and a plane shaves wood. Matching tools to their purposes is the heart of the Shop Information subtest. For tight or recessed fasteners a socket wrench is often best, while an adjustable wrench fits a range of sizes. The wrench is the go-to tool for turning bolts and nuts.
