Tired of Troubles on Fasteners Purchasing? We've Got All Fixes Ready!
Whether for personal use, wholesale/trading, or resale by retail stores, we can provide corresponding solutions.
Dimensions and Thread Specifications
The rivet nuts are available in a wide range of standard thread sizes from M3 to M12. The flat head design has a low profile height of approximately 0.8 to 1.8mm, allowing for a near flush installation.
The half hexagon body provides six contact points for secure gripping within the base material. The small countersunk head variant is designed to sit perfectly flush with the material surface, making it ideal for applications with space constraints or aesthetic requirements.
- Thin Material Fails to Hold Threads: Traditional screws strip in thin sheet metal, causing loose, unreliable connections. Our rivet nuts create a durable, load bearing internal thread that does not rely on the material's thickness.
- Time Consuming Welding or Tapping: Welding nuts is slow, costly, and distorts panels. Tapping requires sufficient material thickness. These rivet nuts install in one simple motion from one side of the workpiece, saving up to 70 percent of installation time compared to welding.
- Loose Assemblies from Vibration: Standard bolts and screws loosen over time. The radial expansion of the rivet nut body during setting creates a permanent interference fit that is highly resistant to vibration induced loosening.
- Rust and Corrosion on Fasteners: Unprotected steel fasteners quickly corrode. The bluish white zinc plating provides a sacrificial protective layer, offering at least three times the corrosion resistance of plain steel, especially important for outdoor or humid applications.
