The DIN1663 Hex Flange Nuts, featuring white, blue zinc plating, or black oxide finishes, are specialized fasteners designed for secure, anti-loosening performance in high-vibration environments. These hex flange nylock nuts integrate a nylon insert for prevailing torque, combined with a wide flange base that distributes load evenly and protects surfaces from damage. Crafted from carbon steel in grades 4.8 to 12.9, with stainless steel options like A2-70 and A4-80 for enhanced corrosion resistance, they offer versatile surface treatments: white and blue zinc for bright, rust-resistant protection, and black oxide for a durable, low-glare finish. Available in metric sizes M4 to M24, these nuts comply with DIN1663 standards and are produced by Duojia in Hebei, China, holding ISO9001, ISO14001, and ISO45001 certifications. Ideal for automotive assemblies, machinery, and industrial installations, they ensure reliable clamping without additional washers, reducing assembly time and costs. With a monthly supply of 10,000 pieces and global export to regions like Europe and Asia, these flange nuts provide superior stability, making them essential for professionals seeking vibration-resistant solutions in heavy and general industries.
Engineered with a hexagonal shape and integrated flange, the DIN1663 Hex Flange Nuts incorporate a nylon locking mechanism that generates friction to prevent loosening under dynamic loads, such as in engines or moving equipment. The surface options—white zinc for a clean, corrosion-resistant layer, blue zinc for added passivation, and black oxide for wear-resistant protection—cater to diverse environmental needs, ensuring longevity in indoor or outdoor settings. Manufactured from robust carbon steel or stainless steel, these nuts feature precise metric threading from M5 to M20, with detailed dimensions for flange width, height, and pitch to match standard bolts. Duojia’s quality control includes hardness testing and coating thickness verification, backed by SGS certification for consistency. Installation is simple: align the flange against the workpiece and tighten with a wrench, leveraging the built-in washer-like base for even pressure distribution. Regular maintenance involves inspecting the coating for scratches and repairing with anti-rust agents to maintain integrity. Offered with minimum orders of 100 pieces and 14-30 day delivery, packaged in cartons or pallets, these nuts are exported worldwide, supporting efficient fastening in automotive, construction, and machinery sectors.

These DIN1663 Hex Flange Nuts stand out with their innovative flange design, which acts as a built-in washer to distribute pressure and prevent surface marring, while the nylon insert provides effective anti-loosening torque for vibration-heavy applications. Surface finishes include white zinc for bright corrosion protection, blue zinc for enhanced passivation against oxidation, and black oxide for a matte, abrasion-resistant coating that minimizes glare. Made from high-strength carbon steel or stainless steel, they offer excellent tensile properties across grades, with smooth threading for easy installation and secure fits in sizes M4 to M24. Duojia’s eco-friendly production ensures quality through ISO-certified processes, including customization for unique thread designs or coatings. The flange enhances stability without needing separate components, reducing assembly complexity, and the nuts resist over-tightening to preserve thread integrity. Their compact yet robust build supports high loads in confined spaces, making them ideal for visible or high-wear areas where durability and aesthetics are key, positioning them as a top choice for reliable fastening in demanding conditions.
DIN1663 Hex Flange Nuts with white/blue zinc and black oxide finishes are versatile for applications requiring load distribution and vibration resistance in various industries. In automotive manufacturing, they secure engine components, chassis parts, and suspension systems, where the flange prevents bolt rotation and the nylon lock ensures hold during high-speed vibrations. Machinery and industrial equipment use them for assembling moving parts like conveyor belts and pumps, benefiting from the corrosion-resistant zinc platings in humid environments or black oxide for heavy-duty, oil-exposed settings. Construction projects employ these nuts in structural framing and metalwork, leveraging the flange to protect materials and distribute stress evenly. In electronics and appliance assembly, they provide stable fastening without additional washers, ideal for vibration-prone devices. Outdoor installations, such as fencing or signage, utilize the protective coatings for weather resistance. Duojia’s globally exported products support custom uses in marine and agricultural equipment, with easy inspections and repairs enhancing longevity. This adaptability promotes safety and efficiency, minimizing failures in both professional and general projects across regions like North America and Europe.
