Hex keys (also referred to as Allen keys/Wrenches) are special hand tools designed to loosen or tighten hexagonal head fasteners like screws and bolts. They are found in any toolbox or household and are called hex due to their use of six contact points, which allows them to grab the Allen key easily. These keys feature a ball end that makes them much easier to operate in difficult-to-access spots. In addition, they come in various sizes, lengths, shapes, and designs.
