Abstract (en)
[origin: WO2022250671A1] A self-clinching and self-piercing construction element for attachment to a plastically deformable metal panel. The construction element includes a body portion with a central axis and a punch portion being coaxial with the central axis and extending from the body portion. A pilot embossment is coaxial with the central axis and extends from the body portion such that the pilot embossment is concentrically disposed between an annular-shaped surface of the body portion and the punch portion. The pilot embossment being configured to engage and plastically deform the metal substrate such that the metal substrate flows into a recessed pocket defined in an outer peripheral surface of the punch portion. A plurality of spaced apart lugs axially project outwards from the annular-shaped surface and extend radially outwards from the pilot embossment.
