Metric Class 8 Hex Serrated Flange Nut, DIN 6923, Zinc-Yellow CR+6
Our Metric Class 8 Hex Serrated Flange Nuts manufactured to DIN 6923 with a Zinc‑Yellow CR+6 finish are designed to deliver reliable locking performance, corrosion resistance, and efficient installation in general‑purpose and medium‑duty metric fastening applications. Produced from carbon steel and heat‑treated to property class 8, these flange nuts provide dependable strength and clamp load capability for a wide range of industrial and mechanical assemblies.
The serrated flange incorporates radial teeth that bite into the mating surface during installation, creating resistance to loosening caused by vibration and movement. This integrated locking feature eliminates the need for a separate washer while improving joint stability. The Zinc‑Yellow CR+6 (hexavalent chromium) plating offers enhanced corrosion protection and a distinctive yellow appearance, making these nuts suitable for indoor and light‑to‑moderate outdoor environments.
Engineered for performance and installation efficiency, DIN 6923 Class 8 Zinc‑Yellow Hex Serrated Flange Nuts are commonly used in machinery, equipment manufacturing, automotive components, enclosures, and general industrial maintenance. The serrated flange provides consistent locking without additional hardware, while the Class 8 strength rating supports reliable fastening under everyday service conditions. Available in a full range of metric thread sizes, these flange nuts provide a practical, cost‑effective fastening solution for OEM production, repair, and maintenance operations where vibration resistance and corrosion protection are required.
