Expansion Rivet Nuts Flare Type Tight Clinch Nuts For Thin Sheet Metal

Flare Expansion Clinch Nuts Flat Ultra-Thin Sheet Metal Fasteners

Expansion flare nuts are specialized thin sheet fasteners different from standard press nuts. The flaring expansion structure locks tightly with flat zero-protrusion surface, perfect for appearance parts and ultra-thin precision equipment assembly.

Expansion Principle

After inserting into pre-punched holes, the top end flares outward under pressure, tightly gripping the hole wall through metal deformation. It provides uniform holding force with completely flat surface after installation.

Core Advantages

• Zero protrusion flat surface for high-end appearance assembly
• Excellent adaptability for ultra-thin sheet metal without deformation
• Uniform circumferential locking force avoids partial loosening
• Neat and beautiful equipment surface after installation
• Stable anti-vibration performance for long-term operation

Application Fields

• Flat assembly of equipment appearance and decorative panels
• Ultra-thin chassis and slim digital device structure
• Clean and flat assembly for medical and precision instruments
• High-standard sheet metal products with strict flatness requirements
• Lightweight industrial control and weak current equipment
