Metric Class 8 Hex Flange Nut Din 6923 Zinc Cr+3

Narrow Your Results By:

A Metric Class 8.8 Hex Flange Locknut, conforming to DIN 6923 standards, is a robust and reliable fastener designed to prevent loosening due to vibrations and dynamic loads. It features a hexagonal shape with an integrated flange, offering enhanced gripping power and stability. This locknut is further protected by Clear Zinc Cr3 plating, providing superior corrosion resistance and ensuring long-lasting durability in demanding environments.

Specifications of Metric Class 8.8 Hex Flange Locknut (DIN 6923)

  • Material: Made from medium carbon steel, the Class 8.8 designation indicates the locknut’s material has a tensile strength of approximately 800 MPa (megapascals) and a yield strength of about 640 MPa. This makes the locknut ideal for medium-strength applications, where securing and maintaining tight connections is essential.

  • Flange Design: The hex flange design combines the traditional hex nut shape with an integrated flange. The flange helps distribute the load evenly, preventing damage to the surface it’s fastened to and ensuring a stronger hold. This feature is essential for applications involving higher shear forces or vibration.

  • DIN 6923 Standard: The DIN 6923 standard ensures these locknuts are manufactured to precise specifications for size, material strength, and performance. This uniformity ensures quality and compatibility with other DIN-compliant fasteners in various industrial and mechanical systems.

  • Clear Zinc Cr3 Plating: The Clear Zinc Cr3 (Chromium Trivalent) plating provides excellent corrosion resistance without the environmental concerns associated with traditional Cr6 (Hexavalent Chromium) coatings. This plating protects the locknut from rust and oxidation, making it suitable for use in outdoor, automotive, and heavy-duty industrial environments.

  • Applications: Metric Class 8.8 Hex Flange Locknuts are commonly used in automotive, machinery, structural assemblies, and construction, where high strength and secure fastening are critical.

Conclusion

A Metric Class 8.8 Hex Flange Locknut with Clear Zinc Cr3 Plating and DIN 6923 compliance offers enhanced durability, corrosion resistance, and secure fastening. Its flange design and robust material properties make it an excellent choice for a wide range of medium-duty applications exposed to vibrations and environmental stress.
