Steel Closed End Rivetnuts for Materials up to 7.60mm Thick

The RCCS Round Countersunk Head Closed End Rivetnut is designed to provide a strong, reliable threaded insert in materials up to 7.60mm 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 closed end design, these rivetnuts help protect internal threads from dirt, moisture, and contamination, making them ideal for applications where thread protection and long-term performance are important. The countersunk head sits flush with the material surface when installed correctly, delivering a clean, professional finish.

Ideal for Flush Finish and Protected Thread Applications

RCCS rivetnuts are ideal for applications requiring a flush-fitting threaded insert and additional protection from environmental contaminants. The countersunk head minimises protrusion above the material surface, while the closed end body helps preserve thread integrity in demanding environments.
