The Yellow Zinc Hex Flange Nuts, adhering to DIN 6923 standards, are customizable fasteners featuring a yellow zinc plated (YZP) coating for reliable corrosion resistance and a visually appealing golden finish. These hexagonal nuts integrate a flange that acts as a built-in washer, distributing clamping force to protect surfaces and enhance stability in vibration-heavy environments. Constructed from carbon steel in grades 4.8 to 12.9, with stainless steel options like 304/316 for harsh conditions, they support custom threading in metric sizes M4 to M24, including coarse and fine pitches for tailored applications. The YZP coating provides moderate rust protection suitable for indoor and light outdoor use, making these nuts ideal for automotive, machinery, and construction sectors. Produced by Duojia in Hebei, China, they comply with ISO9001, ISO14001, and ISO45001 standards, ensuring high-quality manufacturing. Serrated flange variants offer extra anti-loosening grip, eliminating the need for separate lock washers. With a supply capacity of 10,000 pieces per month, flexible packaging, and samples available, these custom-threaded nuts deliver versatile, cost-effective solutions for engineers seeking durable hardware that combines functionality with aesthetic and protective qualities in general and heavy industry settings.
Engineered with a hexagonal shape and extended flange, the Yellow Zinc Hex Flange Nuts undergo YZP galvanization to create a uniform, yellow-tinted layer that resists corrosion while maintaining lubricity for smooth installation. Available in carbon steel or stainless steel, these nuts feature customizable threads from M5 to M20, with options for serrated flanges that bite into surfaces for superior vibration resistance. Duojia’s production includes advanced testing for coating thickness and hardness, backed by SGS certification to guarantee performance. Installation requires matching the nut to a compatible bolt, aligning the flange with the workpiece, and tightening with a wrench—avoid over-torquing to preserve the YZP finish, especially on serrated models which may mark soft materials like wood. For maintenance, inspect the coating regularly and repair scratches with anti-rust paint to extend lifespan. These nuts excel in light industry assemblies, such as furniture or pipeline connections, where the flange protects delicate surfaces. Offered with minimum orders of 100 pieces and delivery in 14-30 days, packaged in cartons or pallets, they are exported worldwide, providing reliable, customizable fastening for automotive chassis, machinery components, and structural applications.

These Yellow Zinc Hex Flange Nuts stand out with their customizable threading, allowing precise adaptations for unique bolt requirements, while the YZP coating delivers a bright, corrosion-resistant surface that enhances visibility and durability. The integrated flange design spreads load evenly, safeguarding materials like wood or plastic, with serrated options providing built-in locking to combat vibrations without extra hardware. Made from robust carbon steel or stainless steel, they offer high tensile strength across grades, ensuring reliability in dynamic conditions. Duojia’s engineering enables bespoke modifications, including non-serrated flanges for smooth surfaces, all supported by eco-friendly, ISO-certified processes. The YZP finish resists chipping and maintains aesthetic appeal, facilitating easy inspections and reducing maintenance needs. Lightweight construction supports heavy loads without bulk, and the nuts’ versatility accommodates both coarse and fine pitches for optimal fit. This combination of features ensures vibration resistance, surface protection, and long-term performance, making them an excellent choice for applications where customization and moderate environmental protection are essential, delivering value through simplified assembly and extended service life.
Yellow Zinc Hex Flange Nuts are highly adaptable for uses requiring corrosion resistance and secure fastening in varied environments. In automotive industries, they fasten suspension and chassis parts, where serrated flanges prevent loosening from road vibrations and the YZP coating withstands exposure to elements. Machinery sectors apply them in equipment like pumps and conveyors, benefiting from the flange’s protective distribution on vibrating components. Construction and pipeline installations utilize these nuts for structural joins and fittings, with custom threads ensuring compatibility in wood or metal assemblies. Light industry benefits include furniture production and plastic molding, where non-serrated versions avoid surface scratches while providing stable holds. In outdoor settings, such as fencing or signage, the yellow plating offers visibility and rust protection. Duojia’s globally supplied products support specialized projects in agriculture and electronics, with easy maintenance through coating repairs enhancing longevity. Their customizability accommodates unique requirements, promoting safety and efficiency by reducing the need for additional washers and minimizing failures in both heavy-duty and everyday applications across international markets.
