Durable Hex & Torx Key Sets
Hex keys (commonly called Allen wrenches) are six-sided tools to drive bolts and screws with hexagonal sockets in their heads. The tool is formed of a single piece of hard steel and often bent into an "L" shape. They come in many sizes which is what makes hex key sets so popular. The same tool with a torx style end is used to turn fasteners with that style socket end. Sets can be folding with six or more ends included or separately clipped or slotted into a holder.
