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 90º, 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.

The tool is simple, small and light.

The contact surfaces of the screw or bolt are protected from external damage.

There are six contact surfaces between bolt and driver.

Very small bolt heads can be accommodated.

The tool allows the use of headless and recessed-head screws.

The screw can be held by the key while it is inserted into its hole.

The torque applied to the screw is constrained by the length and thickness of the key.

The tool is cheap to manufacture, so it can be included with products requiring end-user assembly.

Either end of the tool can be used to take advantage of reach or torque.
