摘要

An insertion element is to be pressed into a not perforated or pre-holed component, in particular sheet metal part, is described. The insertion element has a head part with a annular surface facing the component and a neck portion which, by the annular surface, i.e. from the component system side, projects. The head part has, furthermore, a surrounding the neck part with a radial distance from the annular surface projecting annular projection and the neck part has a radially outwardly projecting annular bead which, in the form of a continuous annular bead or as a locally interrupted annular bead can be formed, whose tip, an axial distance from the annular surface, which is greater than the axial distance between the tip of the annular projection of the annular surface, the radially inside this projection, and with the latter and the annular bead a material of the component forms pocket receiving.
