AI Technical Summary
Existing round self-piercing rivet nuts have insufficient resistance to torsion and ejection on thin sheet metal, especially when the sheet metal material is embedded with a toothed pattern.
Design a square self-piercing self-tapping nut with a flange and rivet ring on the top surface of the square body. The flange and rivet ring form an inverted conical angle fit. The rivet ring is connected to the central hole of the square body. A thin plate material is embedded at the bottom of the rivet ring to form a tight connection.
It improves the torsional and anti-pull-out properties of thin sheet metal parts, has high connection strength, has less limitation on installation space, and has a better anti-loosening effect than round self-piercing press-fit nuts.
