Summary: Driving hex screws.

Allen wrenches, also known as hex keys, are L-shaped tools with a hexagonal (six-sided) cross-section, designed to drive screws and bolts with a corresponding hexagonal recess in their heads. They are commonly used for fasteners that require a high degree of torque without damaging the fastener head. The hexagonal shape allows for a strong, secure grip, preventing slippage. Allen wrenches come in various sizes to fit different screw and bolt sizes, and they are frequently used in applications like assembling furniture, bicycles, and machinery.
