The HKOS-IMP Hexagon Low Profile Head Open End Rivetnut is designed to provide a strong, reliable threaded insert in materials up to 7.90mm thick. Manufactured from high-quality zinc-plated steel, these Rivetnuts create durable, reusable imperial threads without the need for welding, tapping, or access to the reverse side of the material.
Featuring a hexagonal body, these Rivetnuts provide superior resistance to rotation after installation, making them ideal for applications where high torque loads and vibration may cause conventional round body Rivetnuts to spin. The low profile head sits closer to the material surface than a standard flat head Rivetnut, delivering a clean, professional appearance while minimising protrusion.
Designed for compatibility with standard UNC and imperial fasteners, HKOS-IMP Rivetnuts are widely used throughout North American manufacturing, automotive, agricultural, industrial, and construction industries where inch-based hardware is specified.
Ideal for High Torque and Imperial Thread Applications
HKOS-IMP Rivetnuts are specifically designed for applications requiring maximum resistance to spin-out and compatibility with imperial hardware. The hexagonal body locks securely into a matching hexagonal hole, providing superior anti-rotation performance compared to traditional round body Rivetnuts.
The imperial thread design makes these Rivetnuts ideal for repairing, replacing, or manufacturing assemblies that utilise inch-based fasteners, ensuring compatibility with commonly used UNC bolts and screws.

Why Choose HKOS-IMP Imperial Hexagon Rivetnuts?
HKOS-IMP Rivetnuts combine the strength of zinc-plated steel with the superior anti-rotation performance of a hexagonal body design. Unlike conventional round body Rivetnuts, the hexagonal body mechanically locks into the parent material, helping to prevent spin-out when subjected to higher torque loads.
The imperial thread configuration ensures compatibility with commonly used UNC fasteners, making these Rivetnuts particularly suitable for North American machinery, vehicles, equipment, and OEM manufacturing. Their low profile head provides a professional appearance while maintaining a strong, secure fixing in thin materials.
For applications where thread reliability, anti-rotation performance, and imperial fastener compatibility are essential, HKOS-IMP Rivetnuts offer an effective and dependable fastening solution.
