As shown in fig. 1 to 4, the riveting nut assembly of the present invention comprises a riveting nut 1 and a bolt 2 for cooperating with the riveting nut 1.

The riveting nut 1 comprises a nut head 11, a riveting portion 12 and a step portion 13, wherein an internal thread 111 is arranged at one end, close to the riveting portion 12, of the nut head 11, and a self-tapping portion 112 is arranged at one end, away from the riveting portion 12, of the nut. The length of the self-tapping part 112 along the axial direction is 2-4 screw pitch, and the length of the internal thread 111 along the axial direction is 3-6 screw pitch. In this embodiment, the pitch of the internal thread 111 is 4 pitch.

The riveting nut 1 is a hexagonal riveting nut, namely, the riveting part 12 is of a regular hexagonal prism structure, an inner hole of the riveting part 12 is in a regular hexagon, and six sides of the inner hole are tangent to the internal thread 111. The stepped portion 13 is formed to protrude outward in the radial direction from the edge of the rivet portion 12 on the side away from the nut head 11. Of course, the riveting nut 1 may also be a circular nut, and the riveting nut may be a blind rivet nut or a press rivet nut, and may be applied to different nut application fields.
