Wrench A tool used for gripping objects tightly, known as a wrench, offers mechanical advantage in turning rotary fasteners like nuts and bolts. This helps keep them from turning or loosen their grip. In everyday American English, people call this device a wrench. It comes in two main shapes: open-end wrench and box-end wrench. For Americans, a "spanner" refers specifically to a special tool with small pins around its edge. These tiny pins fit snugly into holes on the object being turned. This way, it prevents any unwanted spinning or movement. High-quality wrenches are made from super-strong alloys called chromium-vanadium tool steels. Manufacturers often create them by hammering out large pieces of steel in a process known as drop-forging. For protection against corrosion and ease of cleaning, many have shiny chrome coatings.
