Knurled Countersunk Head M5 Rivet Nut Drill Size
The recommended drill size for installing a Knurled Countersunk Head M5 Rivet Nut is typically 7.0 mm. This allows for a snug fit that ensures proper deformation and firm anchoring during installation. The knurled body enhances anti-rotation performance by biting into the material, while the countersunk head sits flush with the surface, making it ideal for applications where a smooth finish is desired.
Thread Size: M5
Material: Carbon Steel (Zinc-Plated for corrosion resistance)
Head Style: Countersunk Head – for a flush, clean finish after installation
Body Style: Knurled Body – improves grip and prevents spinning in the hole
Grip Range: 0.5 mm – 3.0 mm (varies by specification)
Recommended Drill Size: 7.0 mm
Hole Tolerance: +0.1 mm / -0.0 mm for optimal fit
Installation Tool: Manual or pneumatic rivet nut tool
Automotive panels and bodywork – where low-profile threading is needed
Electrical and electronic enclosures – ensuring secure fastening in sheet metal
Metal furniture assembly – flush finish for aesthetic and functional purposes
Aluminum and plastic housings – where added grip is essential
HVAC systems and ducting – lightweight and vibration-prone installations
Appliance manufacturing – strong, clean threads without welding
This rivet nut is ideal for thin materials (0.5–3.0 mm) and is typically installed using a 7.0 mm drill bit for precise and secure placement.
1. What is the correct drill size for an M5 knurled countersunk head rivet nut?
The recommended drill size is 7.0 mm. This ensures a tight, interference fit that allows the knurled body to grip the material securely and resist spinning.
2. What material thickness can this rivet nut be used with?
Typically suitable for sheet materials between 0.5 mm and 3.0 mm. Always check the grip range of your specific rivet nut model before installation.
3. Can I use this rivet nut in plastic or soft aluminum?
Yes. The knurled body enhances anti-rotation performance, making it ideal for use in softer materials such as plastics, composites, and soft metals.
But the one most suitable for soft materials is jack nuts, because it is a nut specially designed for soft materials.
4. Do I need a special tool to install it?
A rivet nut tool (manual or pneumatic) is required for proper installation. The tool pulls the threaded shank to expand the rivet nut and lock it in place.
5. What’s the advantage of the countersunk head design?
The countersunk head sits flush with the surface, offering a clean, low-profile finish. It’s perfect for visible applications or where components need to sit flat over the installed nut.
6. Is this rivet nut reusable after installation?
While the rivet nut itself is not reusable, the threaded hole can accept and release screws multiple times, making it ideal for removable fastenings.
