Abstract
The invention relates to a functional element (10) comprising a longitudinal axis (14), a body part (16), a hollow pressed part (18), an annular supporting surface (20) which is arranged on the body part, substantially extended in a perpendicular direction with respect to the longitudinal axis and is radially displaced away from the pressed part and an annular groove (21) which axially extends and is embodied in the body part radially inside the supporting surface. Locking ribs (26) are preferably provided and at least partly cross the annular groove and the free end (28) of the pressed part is provided with a annular cutting edge (30). The inventive functional element is characterised in that an annular bulge (32) is embodied on the pressed part between the annular supporting surface and the free end of the pressed part and an annular cavity (34) is embodied around said pressed part between the bulge and the front free end thereof. An assembling component consisting of the functional element combined with a metal sheet, a method for producing the assembling component and a method for producing the functional element are also disclosed.
