Steel Open Hexagon Rivetnuts for Materials up to 7.90mm Thick

The HKOS-J Steel Open Hexagon 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 metric threads without the need for welding, tapping, or access to the reverse side of the material.

Featuring a hexagon body, these rivetnuts provide exceptional resistance to rotation when installed into a correctly sized hexagonal hole, making them ideal for applications subjected to vibration or higher torque loads. The small head (low profile) design reduces surface protrusion while maintaining excellent clamping strength, providing a neat and professional finish.

Ideal for High-Torque and Anti-Rotation Applications

HKOS-J rivetnuts are designed for demanding fastening applications where standard round rivetnuts may be prone to spinning. The hexagonal body helps lock the rivetnut into the parent material, while the open-end design allows the use of longer fasteners when required.
