Metric Class 8 Hex Flange Nut Din 6923 Zinc Cr+3
The metric Class 8.8 hex flange locknut with DIN 6923 specification and Clear Zinc Cr3 plating is a high-performance, all-metal fastening solution ideal for demanding mechanical and structural applications. Engineered for strength and ease of installation, these locknuts feature an integrated wide flange base that acts as a built-in washer to distribute load and resist loosening from vibration or torque.
Made from Class 8.8 medium carbon steel, these flange nuts deliver excellent tensile strength and wear resistance, making them ideal for automotive, machinery, construction, and heavy equipment applications. The DIN 6923 standard ensures consistent quality and compatibility with metric hardware systems, providing peace of mind for engineers and builders seeking dependable, internationally recognized specifications.
The clear zinc Cr3 plating adds an additional layer of protection against rust, oxidation, and environmental corrosion, while also offering a clean, silver finish. The trivalent chromium (Cr3) coating is RoHS-compliant, making it a safer, more sustainable option without compromising on durability. This plating is perfect for both indoor and outdoor use in moderately corrosive environments.
