Hexagonal blind hole rivet nuts are precision fasteners with a head featuring a non-slip toothed flange, a hexagonal shank, and a closed blind hole at the end. The inner hole has a standard metric machine thread, with common sizes ranging from M3 to M12. These products are manufactured using high-quality low-carbon steel, medium-carbon steel, alloy steel, 304 stainless steel, 316 stainless steel, brass, and aluminum alloys. They are available with various surface treatments, including environmentally friendly blue-white zinc plating, color zinc plating, black zinc plating, environmentally friendly nickel plating, zinc-nickel alloy plating, Dacromet coating, electrophoresis, PVD, and stainless steel passivation, ensuring corrosion resistance and aesthetics in various environments. Their structural design provides excellent waterproof and dustproof performance, making them suitable for various scenarios requiring waterproof and dustproof applications, such as sheet metal connections, automotive interior component fixing, outdoor equipment frame installation, electronic device housing assembly, and furniture panel connections. They effectively achieve secure connections between sheet metal parts and offer convenient and efficient installation.
