The invention relates to a plastic nut to be fitted to a component having an aperture, which, with a nut piece serving to hold a screw, can be plugged into the aperture and which, in order to bear on one side of the component, is provided with a flange which has a through hole for the screw and, on its side facing the component, has a sealing washer and, in order to bear on the other side of the component, is provided with snap-action hooks which, after insertion, spread out as the screw is tightened in the accommodation hole in the plastic nut and therefore secure the plastic nut to the component. The sealing washer has at its outer rim a shoulder which encloses the flange and projects beyond the thickness of the latter and, from its inner rim, merges into a collar which projects into the through hole.
Plastic nut to be fitted to a component (1) having an aperture (2), which includes a nut piece (11) adapted for insertion into the aperture (2) and which has an insertion hole (22) that serves to hold a screw (28), a flange (3) to bear on one side (4) of the component (1), wherein the flange (3) has a through hole (10) for the screw (28), an outer edge, a surface facing the component, and a surface facing away from the component, a separate sealing washer (6) integrally provided on a side of the flange (3) facing the component (1), and snap-action hooks (12, 13) to bear on an opposite side (14) of the component (1) and which, after insertion, spread out as the screw (28) is tightened in the insertion hole (22) in the plastic nut to secure the plastic nut to the component (1), characterized in that the sealing washer (6) includes a shoulder and a collar and encloses the flange (3) with the shoulder (7) of the sealing washer embracing the outer edge of the flange (3) and the collar (9) of the sealing washer projecting into the through hole (10), wherein the shoulder (7) of the sealing washer is beveled on an inner side in such a way that its thickness decreases in the direction away from the nut piece (11).
Plastic nut to be fitted to a component (1) having an aperture (2), which includes a nut piece (11) adapted for insertion into the aperture (2) and which has an insertion hole (22) that serves to hold a screw (28), a flange (3) to bear on one side (4) of the component (1), wherein the flange (3) has a through hole (10) for the screw (28), an outer edge, a surface facing the component, and a surface facing away from the component, a separate sealing washer (6) integrally provided on a side of theflange (3) facing the component (1), and snap-action hooks (12, 13) to bear on an opposite side (14) of the component (1) and which, after insertion, spread out as the screw (28) is tightened in the insertion hole (22) in the plastic nut to secure the plastic nut to the component (1), characterized in that the sealing washer (6) includes a shoulder and a collar and encloses the flange (3) with the shoulder (7) of the sealing washer embracing the outer edge of the flange (3) and the collar (9) of the sealing washer projecting into the through hole (10), wherein the shoulder (7) of the sealing washer merges into a sealing lip (17) oriented towards the nut piece (11).
Plastic nut to be fitted to a component (1) having an aperture (2), which includes a nut piece (11) adapted for insertion into the aperture (2) and which has an insertion hole (22) that serves to hold a screw (28), a flange (3) to bear on one side (4) of the component (1), wherein the flange (3) has a through hole (10) for the screw (28), an outer edge, a surface facing the component, and a surface facing away from the component, a separate sealing washer (6) integrally provided on a side of the flange (3) facing the component (1), and snap-action hooks (12, 13) to bear on an opposite side (14) of the component (1) and which, after insertion, spread out as the screw (28) is tightened in the insertion hole (22) in the plastic nut to secure the plastic nut to the component (1), characterized in that the sealing washer (6) includes a shoulder and a collar and encloses the flange (3) with the shoulder (7) of the sealing washer embracing the outer edge of the flange (3) and the collar (9) of the sealing washer projecting into the through hole (10), wherein a region of the flange (3) that is covered by the sealing washer (6) faces the component (1) and is provided with protrusions (21).
Plastic nut to be fitted to a component (1) having an aperture (2), which includes a nut piece (11) adapted for insertion into the aperture (2) and which has an insertion hole (22) that serves to hold a screw (28), a flange (3) facing one side (4) of the component (1), wherein the flange (3) has a through hole (10) for the screw (28), a separate sealing washer (6) integrally provided on the side of the flange (3) facing the component (1), and snap-action hooks (12, 13) to bear on an opposite side (14) of the component (1) and which, after insertion, spread out as the screw (28) is tightened in the insertion hole (22) in the plastic nut to secure the plastic nut to the component (1), characterized in that the sealing washer (6) encloses the flange (3) completely on upper and lower sides of the flange (3) having at its outer edge a shoulder (7), and its inner rim a collar (9) projecting into the through hole (10), whereby a region of the flange (3), which faces the component (1), is provided with protrusions (21) and the outer rim of the shoulder (7) merges into a sealing lip (17) oriented towards the nut piece (11).
