Hex Flat Head M6 Rivet Nuts
Hex Flat Head M6 Rivet Nuts are engineered for high-torque, anti-rotation performance in metal, plastic, and composite materials. Featuring a hexagonal body that fits snugly into pre-punched hex holes, they offer exceptional resistance to spinning under load. The flat head design ensures a flush finish on the surface, making them ideal for visible applications where aesthetics and strength are equally important. Available in steel or stainless steel, they are commonly used in automotive, electrical enclosures, and heavy-duty machinery assemblies.

1. What is the recommended hole size for installing Hex Flat Head M6 Rivet Nuts?
The recommended hole size is typically 9.0 mm, but it may vary slightly depending on the material thickness and rivet nut design. Always refer to the manufacturer’s specification sheet.
2. What makes the hex body design better than a round body?
The hex body provides superior anti-rotation performance, especially in soft or thin materials. It locks into the hole and prevents the rivet nut from spinning during tightening.
3. Can I install Hex Flat Head M6 rivet nuts in plastic or composite materials?
Yes, but ensure the material can withstand the deformation force during installation. Pretesting is recommended, and consider using an insert with larger flange or load spreader if needed.
4. What tools are needed to install these rivet nuts?
A hand or pneumatic rivet nut tool with M6 mandrel is typically required. Some applications may benefit from a hydraulic tool for better consistency in high-volume installations.
5. Are these suitable for outdoor or corrosive environments?
Standard steel may corrode over time. For outdoor use, choose zinc-plated, black-oxide treated, or stainless steel rivet nuts for better corrosion resistance.
