Product Details
These Stainless Steel Hex Flange Nuts come as complete bolt pairs, designed with a Dacromet coating that forms a robust, inorganic film for unmatched resistance to corrosion, heat, and wear—ideal for outdoor or chemical-exposed installations. The stainless steel base material ensures strength and non-reactivity, while carbon steel variants provide cost-effective alternatives with similar grades. Thread sizes range from M3 to M30, supporting precise metric coarse or fine pitches, and the flange expands contact for secure holds without additional hardware. Duojia’s quality assurance includes SGS-certified testing for coating integrity and mechanical properties. For setup, match the nut to the bolt’s specifications, thread on, align the flange, and torque with a wrench—serrated models enhance security but require care on delicate surfaces to avoid marks. In maintenance, check the Dacromet layer periodically and repair minor damage with compatible agents to sustain protection. Versatile for aerospace, automotive suspensions, and structural builds, these pairs are packaged in cartons or pallets, with minimum orders of 100 pieces and 14-30 day shipping. Exported to diverse markets like Europe and Asia, they deliver consistent, high-performance fastening for demanding industrial needs.

Product Features
Equipped with a Dacromet coating, these Stainless Steel Hex Flange Nuts excel in corrosion resistance, offering up to 10 times the protection of standard zinc platings while withstanding high temperatures and chemicals without hydrogen embrittlement. The hexagonal design with integrated flange ensures even load distribution, preventing deformation on workpieces, and serrated variants provide self-locking friction for vibration-heavy uses like machinery or vehicles. Stainless steel construction delivers non-magnetic, hygienic properties, with carbon steel options for balanced strength and affordability across grades. Customizable finishes, including polished or black oxide, allow adaptation to specific needs, and precise threading supports seamless bolt integration. Duojia’s advanced manufacturing minimizes environmental impact, with rigorous testing ensuring coating durability. These nuts resist abrasion in abrasive settings, maintain integrity in saltwater or acidic conditions, and require minimal upkeep, making them suitable for long-term installations. Their compact flange reduces assembly parts, lowering costs and weight, while the overall robustness supports heavy loads in aerospace or construction, delivering a blend of innovation and reliability for demanding applications.
Product Applications
Stainless Steel Hex Flange Nuts with Dacromet coating and bolt pairs are tailored for high-corrosion environments across multiple industries. In automotive sectors, they secure brake systems and suspensions, where the coating combats road salts and vibrations, ensuring safety and longevity. Construction applications include outdoor structural assemblies and bridges, leveraging the flange for load spreading on metal or concrete without rust compromise. Aerospace uses benefit from their lightweight, non-corrosive nature in aircraft components exposed to extreme weather. Marine settings employ them for boat hardware and offshore platforms, resisting saltwater erosion effectively. Chemical plants and machinery manufacturing utilize these for equipment in acidic or humid conditions, with serrated flanges preventing loosening in dynamic operations. Duojia’s products, shipped worldwide, support custom installations in food processing for hygienic, non-contaminating fixes. Maintenance is simple, with repairs preserving the Dacromet layer for extended use, reducing downtime and enhancing operational efficiency in both heavy industry and general projects, from pipelines to renewable energy structures.
