Abstract
Hex keys or like tools of various sizes may be inserted into the gripping aid, to provide a better grip and additional torque when using such tools. The device has an elongated body with hex key accepting slots at each end and longitudinal cavities of different dimensions for an arm of the hex key. In a preferred embodiment, a locking collar to secure the hex key in place in the body is provided. The locking collar has openings extending across its face which rotate from a hex key accepting position to a hex key locking position.
