M8 Hex Rivet Nut Steel Flat Head
The M8 Hex Rivet Nut with a flat head is a heavy-duty fastening solution designed for applications requiring strong resistance to torque and pull-out forces. Its hexagonal body provides excellent anti-rotation performance, especially when installed in pre-punched hex holes, making it ideal for high-vibration environments. The flat head ensures a clean, flush surface after installation, while the M8 internal thread offers compatibility with a wide range of bolts. Made from durable steel, this rivet nut is suitable for thick metals, structural frames, automotive panels, and heavy machinery.
