Stainless Steel Open End Rivetnuts for Materials up to 4.50mm Thick

The KCOI-J Knurled Countersunk Head Open End Rivetnut is designed to provide a strong, corrosion-resistant threaded insert in materials up to 4.50mm thick. Manufactured from high-quality stainless 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 knurled body, these rivetnuts provide enhanced resistance to rotation after installation, helping to create a more secure fixing in demanding applications. The countersunk head sits flush with the material surface when installed correctly, providing a clean, professional finish while maintaining a strong load-bearing thread.

Ideal for Flush Finish and High Grip Applications

KCOI-J rivetnuts are ideal for applications where both a flush-fitting finish and improved anti-rotation performance are required. The knurled body increases grip within the parent material, while the stainless steel construction provides excellent corrosion resistance for indoor and outdoor environments.
