<p>A NUT WITH A C-SHAPED PROFILE, of the type formed by a punched metal sheet folded onto itself for fixing onto a panel, wherein one of the arms, i.e. the upper base, has a hole for the arrangement of a screwed device with at least one thread and wherein the other arm, i.e. the lower base, which is aligned with the axis of the preceding hole, has another hole for receiving the nut tightening screw, said upper base being provided with incisions which define horizontal connecting portions separated from the body of said upper base and longitudinal connecting portions which form an extension of the former and which join together said upper base and lower base, which has a retaining claw which is designed to facilitate application of a tool for slackening the pressure which the nut applies to the panel to which it is fixed; which has a bottom rear flange and side stops on said upper base which form an anti-rotation mechanism when a screw is tightened on the nut; said bottom rear flange freeing from pressure said upper base during assembly on the panel; and said longitudinal connecting portions are overdimensioned, i.e. their height is greater than the sum of the greatest thickness“P”of the panel foreseen for use with said nut and the height“h”of said retaining claw in relation to said lower base.</p> |
