The DIN 6923 Hex Flange Nut with white or blue zinc plating is a versatile fastener engineered for enhanced corrosion resistance and secure load distribution in industrial applications. This hexagonal nut includes an integrated flange that functions as a built-in washer, spreading clamping force to minimize surface damage and improve stability under vibrations. Made from carbon steel in grades 4.8 to 12.9, with stainless steel alternatives like A2-70 for demanding environments, the white zinc plating provides a bright, clean finish with reliable rust protection, while blue zinc offers additional passivation for superior durability. Available in metric sizes M4 to M24 with coarse or fine threads, these nuts meet DIN 6923 standards and are produced by Duojia in Hebei, China, certified under ISO9001, ISO14001, and ISO45001. Serrated flange options enhance anti-loosening grip, making them suitable for automotive chassis, construction frameworks, and heavy machinery. With a monthly output of 10,000 pieces and bulk packaging, these zinc-plated flange nuts ensure cost-effective, long-lasting performance, ideal for professionals needing fasteners that combine aesthetic appeal with robust environmental resistance in both indoor and outdoor settings.
Featuring a hexagonal design with a wide flange base, the DIN 6923 Hex Flange Nut is galvanized with white or blue zinc to form a protective layer that guards against oxidation and wear, ensuring longevity in moist or industrial conditions. The white plating delivers a smooth, reflective surface for easy identification and handling, while blue zinc adds a tinted, enhanced barrier for better corrosion control. Constructed from durable carbon steel or stainless steel, these nuts offer precise threading with pitches from 0.8mm to 2.5mm, compatible with matching bolts for seamless assembly. Duojia’s quality measures include zinc thickness testing and hardness evaluations, supported by SGS certification. Installation is efficient: thread onto the bolt, position the flange against the workpiece, and tighten with a wrench, utilizing serrated versions for extra security without separate washers. For maintenance, inspect the plating regularly and apply anti-rust paint to any scratches to preserve protection. Supplied in cartons or pallets with minimum orders of 100 pieces and delivery in 14-30 days, these nuts are globally distributed, serving sectors like manufacturing and engineering with reliable, vibration-resistant fastening solutions.

These DIN 6923 Hex Flange Nuts boast an innovative flange that integrates washer functionality, evenly distributing pressure to protect workpieces and resist loosening in dynamic conditions. The white zinc plating ensures a glossy, corrosion-resistant surface with excellent adhesion, while blue zinc provides a passivated layer for advanced protection against environmental factors. Built from high-grade carbon steel or stainless steel, they deliver strong mechanical properties with smooth, accurate threads for effortless bolting. Optional serrations on the flange offer superior grip without additional components, ideal for high-vibration setups. Duojia’s customizable production allows for specific finishes and thread types, all verified through ISO-certified testing for consistency. Their design prevents over-tightening damage, maintaining structural integrity, and the zinc coatings enhance visibility for quick inspections. Lightweight and compact, these nuts handle substantial loads while reducing assembly complexity, with eco-conscious manufacturing minimizing waste. This array of attributes makes them a dependable option for applications requiring both functional reliability and a professional, polished appearance.
DIN 6923 Hex Flange Nuts with white or blue zinc plating are essential in scenarios demanding corrosion protection and stable fastening across industries. In automotive assembly, they secure engine parts and suspension systems, where the flange’s load distribution and serrations counter road vibrations effectively. Construction uses include bolting steel beams and frameworks, with zinc plating resisting weather exposure for outdoor durability. Heavy machinery benefits from their application in equipment like compressors and generators, preventing loosening amid constant operation. Electronics and appliance manufacturing employ them for panel attachments, leveraging the clean zinc finish to avoid contamination. In agricultural tools, these nuts fasten implements exposed to moisture, ensuring long-term hold. Duojia’s exported products support global needs in marine fittings and furniture production, with easy maintenance through plating repairs extending usability. Their versatility accommodates both serrated and non-serrated types, optimizing for soft or hard surfaces, thus improving safety and efficiency in professional and general projects worldwide.
