<p>The tool (1) is made of a narrow and flat metal piece and divided into two segments (2, 3) with a cranked intermediate area (8). One of the segments (1) is provided with a number of polygonal openings (9, 10, 11, 12) for the insertion of a matching screw head or nut for being tightened or loosened. The other segment (3) has a longitudinal slot (4) with a central circular area (5) located close to its outer end to be used for tightening or loosing a wing nut. In a second version a wider slot (13, 14, 15) is positioned at the outer end dividing the material into a fork shape (16, 17) in order to be attached to a particularly large wing nut.</p> |
