ANSI/ASME B18.16.4 Hexagon Flange Nut

The ANSI/ASME B18.16.4 Automotive Hexagon Flange Nut is a robust fastening solution engineered to meet the rigorous demands of automotive applications. Designed with a wide flange base, it distributes clamping force evenly across mating surfaces, minimizing the risk of loosening under vibration—a critical feature in dynamic automotive environments. Its hexagonal shape ensures compatibility with standard tools, streamlining assembly and maintenance processes, while the precision-machined threads guarantee secure, backlash-free engagement with bolts. Ideal for high-stress components like chassis systems, suspension assemblies, and brake calipers, this nut combines high tensile strength with corrosion-resistant finishes (such as zinc plating or Dacromet coating) to withstand harsh road conditions and temperature fluctuations. Automotive engineers rely on its reliability for critical connections in transmissions, exhaust systems, and wheel hubs, where consistent performance directly impacts safety and durability. By adhering to strict ANSI/ASME dimensional and material standards, the B18.16.4 ensures seamless integration with existing designs, reducing downtime and enhancing operational efficiency. For manufacturers seeking a trusted, cost-effective fastener that balances strength, precision, and longevity, this hex flange nut stands as a cornerstone of automotive assembly excellence.
