M4 Hex Flat Head Heavy Duty Rivet Nut
The M4 Hex Flat Head Heavy Duty Rivet Nut is a fastener specifically designed for small-thread applications that require high-strength connections. Featuring a hexagonal body, it offers excellent resistance to rotation once installed, ensuring a secure fit in materials such as metal, plastic, or composites. The flat head design allows for a flush and aesthetically pleasing surface finish. As a heavy-duty rivet nut, it can withstand high tensile and shear forces, making it a reliable choice for precision assembly in industrial equipment, small electronic devices, automotive components, and other demanding applications.

Sheet metal fastening
1. What is the purpose of the hex body design?
The hex body provides anti-rotation properties when installed in hexagonal holes. This ensures the rivet nut remains securely in place during and after installation, even under vibration or torque.
2. What type of installation tool is recommended?
For heavy-duty performance and consistent clamping, pneumatic or hydraulic rivet nut installation tools are recommended. Manual tools can be used, but may not deliver sufficient force for optimal clamping in thicker or harder materials.
3. What is the maximum material thickness it can be installed into?
The suitable material thickness depends on the rivet nut’s grip range, which varies by manufacturer. Typically, the M4 size is used for material thickness between 0.5 mm to 2.5 mm. Always check product specifications for exact grip range.
4. Is the flat head visible after installation?
Yes, the flat head sits flush against the surface and is usually visible unless it’s countersunk or hidden by other components.
5. What types of applications is this rivet nut best suited for?
It’s ideal for high-strength, space-limited applications such as automotive panels, electronics enclosures, aerospace equipment, and industrial assemblies.
