Hex wrenches, also known as hex keys or Allen wrenches, are used to fasten bolts and screws with a hexagonal socket. These are handy tools and often come in sets with a range of sizes. Usually made of steel, hex wrenches come with long handles, plastic wrapped handles or as a folding set allowing you to carry it in your pocket. For jobs from large to small, hex keys are a versatile tool that should be in every tool box.
