Abstract
A REMOVABLE AND REUSABLE QUICK NUT, of the type used to fasten panels and/or accessories thereto, principally in the automobile industry, wherein on said nut, originating from a planar base, emerge individual opposite compression tabs that rise and fold toward an inner zone of the nut and that, by means of another fold, invert their direction in order on the outside to return to the height of the base, forming joining surfaces; from said surfaces there originate individual lugs or fins that, by means of successive folds, converge toward the inner zone of the nut in a position designed to engage with the screw thread of the screw for fastening the nut.

A REMOVABLE AND REUSABLE QUICK NUT, said nut being formed by a planar base from which emerge opposite tabs that form part of a means for fastening the nut to a panel, there being a screw threaded hole in a center of said base and said means for fastening the nut to the panel being actuated by an insertion of a fastening screw, CHARACTERIZED in that
- said tabs rise and fold toward an inner zone of the nut and, via a fold, invert their direction to the outside and return to the level of the base, forming joining surfaces;
- there being defined, on said tabs, starting from said surfaces, an outwardly inclined lower portion of the nut, and via a fold, an inwardly inclined upper portion of the nut, said lower portion and said upper portion having opposite inclinations in a direction normal to the longitudinal axis of the screw thread hole;
- from said surfaces, formed at the ends of said tabs, there originate individual lugs or fins that, via elbows, define, originating from the respective surfaces, a first portion slightly outwardly inclined from the standpoint of the center of the nut, and a second portion that converges toward the inner zone of the nut in a position designed to engage with the screw thread of the screw for fastening the nut.
