Carbon Steel Flat Head Hexagon Riveted Nuts
Product Overview
Flat Head Hexagon Riveted Nuts are engineered fastening components designed for secure and permanent installation in sheet materials. Featuring a flat head for flush mounting and an internal hexagon body for anti-rotation properties, these rivet nuts offer a reliable threaded solution where welding or tapping is impractical. Made of high-strength carbon steel, they are widely used in automotive, construction, furniture, and machinery applications where cost-effective yet strong fastening is required.

Material Introduction & Manufacturing Process
Manufactured from premium carbon steel, Flat Head Hexagon Riveted Nuts are optimized for high load-bearing capacity and thread durability. The typical production process includes:
Material procurement & chemical composition analysis
Cold forming for head and body with internal hexagon
Thread tapping with precision-grade tools
Surface treatment (zinc plating or black oxide coating)
100% thread gauge inspection
Sorting, packaging, and labeling
The internal hexagon structure ensures anti-rotation during installation, while zinc plating enhances corrosion resistance for extended product life.
Application Industries & Use Scenarios
Flat Head Hexagon Riveted Nuts are widely applied in:
Automotive chassis and body panel assemblies
Sheet metal housings in electronic devices
Construction steel frameworks
Furniture manufacturing
HVAC units and duct systems
Agricultural and industrial machinery
The flat head profile allows flush fitting into sheet materials without protrusion, making them ideal for aesthetic or space-sensitive applications.
