Definition
An Allen wrench, also known as a hex key, is a tool used to drive screws or bolts with a hexagonal socket in their heads (like Allen screws). It's L-shaped, allowing for increased torque and easy access in tight spaces. Think of it as a specialized key for a specific type of screw. Allen wrenches are commonly used in furniture assembly, bicycle maintenance, and electronics repair. They are simple, durable, and provide a strong grip. The shape of the wrench allows it to apply force efficiently.🔩
