DESCRIPTION
Discover about Closed End Countersunk Knurled Rivet Nuts
Discover the Stainless Steel Closed End Countersunk Knurled Rivet Nuts by RivetGo, engineered for applications requiring a flush finish and waterproof sealing. These rivet nuts feature a closed end to protect against water and dust, making them ideal for harsh environments. Crafted from stainless steel, they offer excellent corrosion resistance for long-lasting performance. Check out other closed end knurled rivet nuts: Closed End Flat Head Knurled Rivet Nuts and Closed End Reduced Head Knurled Rivet Nuts.
Key Features
Unlike open-end rivet nuts, the Closed End Countersunk Knurled Rivet Nuts offer a waterproof rivet nuts design with a closed end, preventing water, dust, and contaminants from entering. The countersunk head ensures a flush finish for improved aerodynamics and aesthetics, while the knurled body provides reliable anti-rotation in softer materials, setting them apart from hexagon designs.
Applications
Perfect for marine rivet nuts applications, automotive components, and outdoor equipment where waterproofing and a smooth surface are essential, these rivet nuts are available in M3 to M12. Pair with our Rivet Nut Tools for easy installation.

TECHNICAL SPECIFICATION
Understanding the Size Chart:
- Thread Size (d): The metric thread size (e.g., M3, M4) compatible with matching bolts or screws.
- Grip Range (e): The range of material thickness the rivet nut can securely fasten (e.g., 0.5-2 mm).
- Hole Size (H): The recommended diameter of the hole to be drilled in the material for installation.
- Head Height (E): The height of the rivet nut head after installation, affecting the protrusion above the surface.
- Head Diameter (B): The diameter of the rivet nut head, determining the contact area with the material.
- Overall Length (L): The total length of the rivet nut before installation.
- Installed Length (L₂): The length of the rivet nut after installation, indicating the space it occupies.

Installation Guide
- Drill a countersunk hole in the material matching the specified Hole Size (H) and countersink angle in the Size Chart.
- Insert the Closed End Countersunk Knurled Rivet Nut into the hole, ensuring the head sits flush with the material surface.
- Use a compatible rivet nut tool to compress and secure the rivet nut, allowing the knurled body to grip the material.
- Thread a matching bolt or screw into the rivet nut, ensuring the bolt length does not exceed the rivet nut’s internal depth.
Note: Ensure the material thickness falls within the specified Grip Range (e) and is at least 1.5mm for a secure fit.
Technical Notes
- Ensure the material thickness is within the Grip Range to avoid installation failure.
- A properly prepared countersunk hole is essential for a flush finish; use a countersink bit matching the head angle.
- The knurled body provides anti-rotation in softer materials; for harder materials, ensure proper hole preparation.
- Closed End design prevents water and dust ingress, making this product ideal for outdoor or marine applications.
- Ensure the bolt length does not exceed the rivet nut’s internal depth to avoid damaging the closed end.
- Recommended for use with stainless steel bolts to prevent galvanic corrosion.
