1. A self-clinching construction element for attachment to a plastically deformable metal substrate, the self-clinching construction element comprising:
a body portion with a central axis, the body portion including an outer peripheral surface extending in a direction of the central axis, and an annular-shaped surface extending in a direction perpendicular to the central axis;
a punch portion being coaxial with the central axis and extending from the body portion, the punch portion including an outer peripheral surface extending in the direction of the central axis;
a pilot embossment being coaxial with the central axis and extending from the body portion such that the pilot embossment is concentrically disposed between the annular-shaped surface and the punch portion, wherein the pilot embossment is configured to engage and plastically deform said metal substrate such that the metal substrate flows into a recessed pocket defined in the outer peripheral surface of the punch portion; and
a plurality of spaced apart lugs collectively encircling the punch portion.
