RCCI Stainless Steel Closed End Countersunk Head Round Rivetnut Metric Thread M3-M12

Stainless Steel Closed End Countersunk Head Round Rivetnut

The RCCI Stainless Steel Closed End Countersunk Head Round Rivetnut is designed to provide strong, reusable internal threads in thin sheet materials, hollow sections, and tubular assemblies where access is only available from one side. Manufactured from stainless steel with a self-colour finish, these Rivetnuts offer excellent corrosion resistance and long-term durability while providing the added benefit of a sealed closed end design.

The countersunk head sits flush with the surface after installation, creating a clean, low-profile finish that is ideal for applications where appearance and clearance are important. The closed end construction helps prevent the ingress of moisture, dirt, dust, and other contaminants while stopping fasteners from protruding through the rear of the insert.

Why Choose RCCI Stainless Steel Closed End Countersunk Rivetnuts?

RCCI Rivetnuts combine the advantages of a flush countersunk head with the protection of a closed end design. The countersunk flange allows the Rivetnut to sit level with the material surface, providing a neat appearance and reducing snag points, while the closed end construction helps protect the rear of the assembly from moisture, dust, and debris.

Manufactured from stainless steel, these Rivetnuts provide excellent resistance to corrosion and wear, making them suitable for both indoor and outdoor applications. They are ideal for engineers, fabricators, manufacturers, and maintenance professionals seeking a durable, sealed threaded insert solution.
