Steel Closed End Rivetnuts for Materials up to 6.00mm Thick

The RFCS-F Round Flat Head Closed End Rivetnut is designed to provide a strong, reliable threaded insert in materials up to 6.00mm 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 closed end design, these rivetnuts help protect internal threads from dirt, dust, moisture, and contaminants, making them ideal for applications where thread protection and long-term reliability are important. The flat head flange provides excellent load distribution and a neat, professional finish for a wide range of engineering and manufacturing applications.

Ideal for Protected Thread and Sheet Metal Applications

RFCS-F rivetnuts are ideal for creating strong load-bearing threads in thin materials where conventional tapping is impractical. The closed end construction helps maintain thread integrity by preventing contamination from entering the threaded section, making them suitable for demanding industrial environments.
