Abstract: A QUICK FASTENING DEVICE FOR PANELS, of the type containing two elements that interact with one another by virtue of the moving parts thereof and which is used to provide an anchoring point for the fastening of an application to the hole in a panel, being formed from a clip and a pin, said clip incorporating tabs descending downwards from the base, and having elastic ability in order to move closer toward the center of said clip through the sliding action of elbows or hooks on said tabs, acting on the inclined profile of cavities provided in said pin.

Abstract: COMPENSATION NUT, of the type used to perform fixing together of two parts which may be joined together at a slightly variable distance while maintaining said distance separating them, used for example in motor vehicles in order to fix the supports of dashboards to the vehicle structure, said nut being formed by a combination of a top part, one or more intermediate nuts and a base clip or nut, which are provided with threads which allow mutual mating thereof and mutual retraction or extension thereof by means of a single screwing operation, said threads each being provided with stops which limit relative displacement thereof.

Abstract: METHOD FOR MANUFACTURING A NUT BY THE PROGRESSIVE PRESS FORGING OF A LAMINAR METAL SHEET AND RESULTING NUT, in which said method comprises the steps of: producing a piece with a supporting washer, a dome and an emergent hexagonal part by press forging starting from a laminar metal sheet of material of suitable thickness, said piece being of uniform thickness; and creating a threaded internal cylinder by progressive press forging of the interior of said hexagonal emergent part, displacing material laterally from the central zones of said faces to the zones of the angles, heat treating the piece obtained, treatment intended to provide the piece with greater strength, especially a yield strength Rp 0.2% of approximately 1200 MPa and a tensile strength Rm of approximately 1400 MPa.

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.
