DESCRIPTION
Discover about Countersunk Head Knurled Rivet Nuts
Introducing the Stainless Steel Countersunk Head Knurled Rivet Nuts by RivetGo, engineered to deliver a seamless flush finish for applications requiring a smooth surface. These rivet nuts are perfect for creating reliable threads in thin materials while ensuring a professional look. Crafted from stainless steel, they offer excellent corrosion resistance for long-lasting performance. Check out other knurled rivet nuts: Flat Head Knurled Rivet Nuts and Reduced Head Knurled Rivet Nuts.
Key Features
Unlike flat head or reduced head options, the Countersunk Head Knurled Rivet Nuts feature a countersunk head that sits flush with the material surface, optimizing aerodynamics and aesthetics. The knurled body provides excellent anti-rotation properties in softer materials, while the design requires a countersunk hole, making it ideal for materials thicker than 1.5mm to maintain structural integrity.
Applications
Perfect for automotive rivet nuts applications like dashboard assemblies, aerospace components, and electronics where a flush finish is critical, these rivet nuts come in M3 rivet nuts to M12 rivet nuts for versatile use. 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 Countersunk Head 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 to complete the assembly.
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.
- Open End design allows flexibility for bolts of varying lengths but is not suitable for waterproof applications.
- Recommended for use with stainless steel bolts to prevent galvanic corrosion.

I needed to bolt the handrail to the saddles. The tube was I bit thin to tap so I used countersunk m5 stainless steel rivnuts. The countersinking meant I could get the handrail to sit down flush with the saddles.
S
We needed these to quickly fit pipe clamps to a stainless steel box section frame that formed part of a pipe fitting training rig for a customer. These were excellent quality, with no failed compressions, when fitted with both manual and pneumatic tooling. Will definitely buy these again in the future.
n
The intended use will be to replace an ugly welded-on hex nut to the base of a custom variable mains AC source. A hex nut was not specified... but that is another story.
