A hex key (also, Allen key and Allen wrench) is a simple driver for screws that have heads with internal hexagonal recesses (sockets).Hex keys are formed from a single piece of hard steel hexagonal rod having blunt ends that fit snugly into similarly-shaped screw sockets.

The rods are bent to 90, forming two arms of unequal length resembling an “L”. The tool is usually held and twisted by its long arm, creating a relatively large torque at the tip of the short arm; it can also be held by its short arm to access screws in difficult-to-reach locations and to turn screws faster at the expense of torque.

Our Hex keys are designated with a socket size and are manufactured with tight tolerances.We offer a variety of screws, and bolts and provide relevant hex keys for all your DIY needs.
