Abstract
A functional element (), for fixing to a piece of sheet metal (), such as for example, a nut element or a bolt element with a body section or head section, comprising an annular flange () which transforms into a cylindrical rivet section, is characterised in that the transformation from annular flange into the rivet section is formed by an at least essentially conical surface, forming a contact surface for a corresponding conical region of a piece of sheet metal, which, on fixing the functional element to a piece of sheet metal, is clamped between the side of the annular flange facing the rivet section and an annular bead () formed from the rivet section. An assembled component and a method for the fixing of a functional element are also disclosed.
