Aluminium Closed End Rivetnuts for Materials up to 6.50mm Thick

The RCCA-G Round Countersunk Head Closed End Rivetnut is designed to provide a lightweight yet reliable threaded insert in materials up to 6.50mm thick. Manufactured from high-quality aluminium, 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 debris, while the countersunk head sits flush with the material surface when installed correctly. This combination makes them an excellent choice for applications requiring both a neat appearance and a secure threaded fixing.

Ideal for Lightweight and Flush Finish Applications

RCCA-G rivetnuts are ideal for applications where weight reduction is important without compromising fastening performance. The aluminium construction offers excellent corrosion resistance and ease of installation, while the countersunk head provides a clean, professional finish.
