The invention provides a self-stamping nut element and an assembly component comprising the nut element and a sheet metal section. The stamping nut element with intensity of 700MPa-900MPa is designed to be pressed into the sheet metal section, characterized in that: the nut element self-stamping hole is attached and enters into the metal sheet with higher intensity or the metal sheet with thickness of more than 3.5mm and the nut element is designed that: the stamping hole comprises a circulating groove underneath a sheet metal contact surface and a stamping edge at a free front side. The stamping edge is spaced from limitation of the groove adjacent to the edge by a peripheral surface with an axial level, which corresponds to at least 30%, preferably 50% of the metal sheet thickness. Radial wall thickness of the stamping section within area of the free front side from outer side of the section to nominal diameter of a thread corresponds to thickness between 1.2-1.8 and 1.5 times of sheet metal part thickness.
