Abstract
The invention relates to a rotationally symmetrical plastic nut part, insertable into a penetration in a metal plate, for a fastener, more particularly a screw, adapted to be received by a hole in the nut part, with a flange, said flange being adapted to be brought into contact with the metal plate. A coaxial metal ring is embedded in the flange, a front side of said metal ring being adapted to be brought into contact with the surface of the metal plate, wherein, upon rotation of the nut part together with the metal ring, the metal ring is adapted to be joined by friction-welding to the metal plate.
