  • Patent number: 4969788
    Abstract: The invention relates to a nut with a pressure ring in which the pressure ng is provided with a spherically shaped underside for engagement with a depression complementary thereto in a component to be secured. In order to permit a simple and secure mounting of the nut with the pressure ring and to guarantee a clearly reproducible holddown force, the pressure ring (12) is formed as a closed ring and means (18, 19), such as for example a peripheral rim and a circumferential flange, are provided for connecting the nut (10) with the pressure ring (12) which prevents a separation and loss. Thereby the nut and ring are rotatable relative to one another about a nut axis (1) and are shiftable relative to one another transversely of the nut axis (1). The peripheral rim (18) for connecting the nut (10) and the pressure ring (12) is so arranged on the first of these two elements that it engages in overlapping relationship the circumferential flange (19) on the second element (12) with radial and axial freeplay.
