FRN (Flanging Rivet Nut) is a specialized rivet nut designed for high-strength fastening, featuring a unique flanged structure that excels in withstanding vibration, impact loads, and high axial forces.
Core Structural Features
• Equipped with wedge-shaped teeth, a flange concave surface, and a triangular rib anti-rotation structure to prevent loosening during use.
• During installation, the expanding rivet mouth is pressed into the plate hole by a press; the thin plate is squeezed into the nut's groove under force, while the wedge-shaped ribs embed into the metal plate, forming a secure and non-slip mechanical bond.
Performance Advantages
• Superior load resistance: Outperforms standard rivet nuts or expansion rivet nuts in scenarios involving vibration, impact, or high axial force.
• Precision alignment: Offers better geometric tolerances after installation compared to welded nuts, avoiding deformation caused by high-temperature welding.
Typical Application Fields
• Primarily used in automotive chassis, airbag assemblies, and other structural components-areas where connection strength and reliability are critical to safety and performance.
