Metric Class 10 Hex Flange Nut, Non Serrated, DIN 6923, Zinc CR+3
Our Metric Class 10 Hex Flange Nuts manufactured to DIN 6923 with a Zinc CR+3 finish are high‑strength fastening components designed for demanding mechanical and structural applications where reliable clamp load and corrosion resistance are required. Produced from carbon steel and heat‑treated to property class 10, these flange nuts provide greater tensile strength and load‑bearing capability than Class 8 alternatives.
The non‑serrated flange functions as an integrated washer, evenly distributing load across the mating surface without damaging coatings or softer materials. This design eliminates the need for a separate washer, reducing part count and simplifying installation. The Zinc CR+3 (trivalent chromium) plating provides corrosion protection suitable for indoor and light‑to‑moderate outdoor environments while meeting modern environmental compliance standards.
Engineered for strength and installation efficiency, DIN 6923 Class 10 Zinc CR+3 Hex Flange Nuts (Non‑Serrated) are commonly used in machinery, equipment manufacturing, automotive assemblies, structural components, and industrial maintenance applications. The flange design improves joint stability and load distribution, while the Class 10 strength rating supports high clamp loads in critical fastening points. Available in a full range of metric thread sizes, these flange nuts deliver dependable performance for OEM production, repair, and heavy‑duty service environments.
