Abstract: A self-adjusting-size socket formed as a pair of coaxial tubes in rotatable relationship to one another, the innermost tube having a limited directional distance and independently rotational relationship with the outer tube by rotating along a mated set of threaded structures on immediately adjacent sides of the coaxial pair of tubes. The inner tube is a deep well chamber having a tool receiving end and a fastener receiving end, with an annular array of independently pivotable fingers arranged about an internal perimeter of the inner tube at the fastener receiving end. Rotation of the inner tube pushes a lowermost portion of the inner tube against the fingers, pushing them into the deep well chamber and around an irregularly shaped bolt or nut style fastener, gripping the fastener and allowing a user to remove or reinstall the fastener. The fingers self-adjust around the fastener.
