Premium 316 Stainless Steel Open End Rivetnuts for Materials up to 4.50mm Thick
The RCOI-CD316 Round Countersunk Head Open End Rivetnut is a premium fastening solution designed to create strong, corrosion-resistant metric threads in materials up to 4.50mm thick. Manufactured from 316 stainless steel, these Rivetnuts provide exceptional durability and long-term performance in environments where standard steel or stainless steel fasteners may be unsuitable.
Designed for installation from one side of the material, the RCOI-CD316 eliminates the need for welding, tapping, or access to the reverse side of the workpiece. The countersunk head design sits flush with the material surface when installed correctly, delivering a clean, professional finish ideal for high-quality engineering and fabrication projects.
Ideal for Marine and Corrosive Environments
Manufactured from premium A4 / 316 stainless steel, the RCOI-CD316 offers outstanding resistance to saltwater, chemicals, moisture, and harsh weather conditions. This makes it the preferred choice for marine, offshore, food processing, architectural, and outdoor applications where maximum corrosion resistance is essential.
The open end design also allows the use of longer bolts and threaded fasteners, providing greater flexibility across a wide range of installations.
