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. For seamless installation, explore our collection of Manual Rivet Nut Tools for precision in smaller projects or our Rivet Nut Guns collection for high-efficiency fastening in large-scale operations.

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.

ADDITIONAL RESOURCES
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.
