The invention relates to a rivet nut (10) with a base part (12) and a cylindrical rivet section (14), the base part having a central threaded cylinder (16), an annular contact surface (18) that is coaxial to the threaded cylinder on a plane (20) perpendicular to the longitudinal axis (22) of the threaded cylinder, and that has an axially aligned annular groove (24), said groove being arranged radially inside the annular contact surface (18) and radially outside the cylindrical rivet section (14) and said groove blending, on the radially inner side, into the outer surface of the cylindrical rivet section, and anti-rotation ribs (42) being provided in the area of the annular groove. The invention is characterized in that the annular groove, when seen in an axial cross-sectional plane, has a U-shaped cross-section with a radially outer lateral wall (30) which is relatively steep and which has, at the steepest point (33), an inclination to the center longitudinal axis of the rivet nut in the range of approximately 45° to approximately -20°, preferably of approximately 30° to approximately 0°. |
