Steel Open Hexagon Rivetnuts for Materials up to 8.00mm Thick

The HFOS-CD Steel Open Hexagon Rivetnut is designed to provide a strong, reliable threaded insert in materials up to 8.00mm thick. Manufactured from high-quality zinc-plated steel, these rivetnuts create durable, reusable metric threads without the need for welding, tapping, or access to the reverse side of the material.

Featuring a hexagon body, these rivetnuts offer superior resistance to rotation when installed into a correctly sized hexagonal hole, making them ideal for applications where higher torque loads and vibration resistance are important. The flat head design provides maximum load distribution across the material surface while delivering a strong, secure fastening solution.

Ideal for High-Torque and Anti-Rotation Applications

HFOS-CD rivetnuts are designed for demanding fastening applications where conventional round body rivetnuts may be prone to spinning. The hexagonal body helps lock the rivetnut firmly into the parent material, providing increased resistance to rotation and improved long-term performance.
