Metric Class 8 Hex Serrated Flange Locknut, Din 6923, Zinc Cr+3

Narrow Your Results By:

A Metric Class 8.8 Hex Serrated Flange Locknut, compliant with DIN 6923 standards, is a high-performance fastener commonly used in mechanical and structural applications. It combines a hex nut with a serrated flange, designed to prevent loosening under vibration or dynamic loads. This locknut is plated with Clear Zinc Cr3, offering corrosion resistance and durability for use in a variety of harsh environments.

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

  • Material: These locknuts are typically made from medium carbon steel, ensuring strength and reliability. The Class 8.8 designation refers to the material’s tensile strength, which is approximately 800 MPa (megapascals), and its yield strength, which is about 640 MPa. This makes it ideal for applications that require high strength and durability.

  • Serrated Flange: The unique serrated flange design provides additional grip on the surface it is fastened to, creating resistance to loosening even under vibrations. This makes the locknut especially useful in automotive, industrial, and machinery applications.

  • DIN 6923 Standard: This standard specifies the dimensions, mechanical properties, and characteristics of serrated flange locknuts. Following DIN 6923 ensures uniformity, quality, and performance across industries that require secure fastening solutions.

  • Clear Zinc Cr3 Plating: The Clear Zinc Cr3 (Chromium Trivalent) plating offers excellent corrosion resistance, protecting the fastener from rust, oxidation, and environmental degradation. Unlike hexavalent chromium plating, Cr3 is more environmentally friendly, making it a safer option for industrial applications.

  • Applications: Metric Class 8.8 Hex Serrated Flange Locknuts with Clear Zinc Cr3 plating are widely used in automotive, machinery, construction, and structural assemblies. Their resistance to corrosion and vibration makes them ideal for heavy-duty environments.

Conclusion

A Metric Class 8.8 Hex Serrated Flange Locknut with Clear Zinc Cr3 Plating and DIN 6923 compliance provides superior strength, corrosion resistance, and reliability. Its serrated flange design prevents loosening, ensuring secure and durable fastenings in challenging environments.
