Allen Keys (Hex Keys / Hex Wrenches) are hand tools designed for driving screws and bolts with hexagonal sockets. Installation involves inserting the short or long arm of the L-shaped key into the hex socket and applying torque to tighten or loosen the fastener efficiently and accurately.

Allen Keys are widely used in furniture assembly, machinery maintenance, automotive applications, and general engineering tasks. Made from high-quality steel, they offer excellent durability, precise fit, and reliable performance for repetitive fastening operations.
