Product Details
These Copper Brass Hex Flange Nuts come as a complete bolt pair, designed for seamless integration in assemblies demanding non-ferrous materials. The brass or copper construction provides inherent corrosion resistance, making them suitable for humid or chemical-exposed environments without the need for additional coatings. The flange expands the contact area, minimizing pressure on surfaces and offering built-in washer functionality, while the hexagonal shape ensures easy wrenching. Thread options include metric coarse pitches from 0.8mm to 2.5mm and fine variants for precise fits, compatible with bolts of the same size and grade. Duojia’s production process includes rigorous quality checks via SGS certification, ensuring consistency in dimensions like flange diameter and height. Installation involves matching the nut to the bolt, aligning the flange with the workpiece, and tightening carefully to avoid deforming the softer brass material. Maintenance is straightforward: clean regularly and apply protective oil in moist conditions to sustain the plain finish’s integrity. Packaged in small packs, cartons, or pallets, these pairs support minimum orders of 100 pieces with 14-30 day delivery, and are exported globally to markets in Asia, Europe, and beyond, catering to industries prioritizing conductivity and longevity.

Product Features
Distinguished by their non-ferrous copper or brass composition, these DIN 6923 Hex Flange Nuts with bolt pairs excel in conductivity and corrosion resistance, ideal for electrical or marine applications where steel alternatives might fail. The plain finish maintains the materials’ natural luster and properties, avoiding coatings that could interfere with soldering or heat transfer. The flange design incorporates friction-enhancing elements for vibration resistance, distributing loads to prevent loosening without serrations that might mar delicate surfaces. Customizable threads in metric or imperial standards allow for tailored fits, while the softer yet durable brass ensures easy machining and installation. Duojia’s engineering supports unique customizations, backed by ISO certifications for quality assurance. These nuts resist oxidation in humid conditions, offer low magnetic permeability for sensitive electronics, and provide thermal stability in high-heat environments. Their lightweight nature reduces overall assembly weight, and the paired bolt setup simplifies procurement, making them efficient for bulk use. Overall, these features combine to offer a versatile, maintenance-friendly fastener that prioritizes performance in non-contaminating, conductive scenarios.
Product Applications
Copper Brass Hex Flange Nuts with bolt pairs are perfectly suited for applications in corrosion-sensitive and conductivity-dependent fields. In plumbing systems, they secure fixtures and pipes, leveraging brass’s anti-rust properties to withstand water exposure without contamination. Electronics and electrical equipment benefit from their low magnetic interference and excellent conductivity, ideal for circuit boards, wiring harnesses, and grounding components. Marine accessories use them for boat fittings and hardware, where the materials resist saltwater degradation and maintain integrity in harsh ocean conditions. Food processing machinery employs these nuts for hygienic assemblies, as copper’s antimicrobial qualities prevent bacterial growth in sanitary environments. Additionally, they support decorative or architectural projects, providing a polished, aesthetic finish for visible installations. Duojia’s globally exported products facilitate custom uses in automotive electrical systems or renewable energy setups, with simple maintenance like oil application ensuring longevity. This range of applications enhances reliability and safety, reducing failures in specialized industries while promoting efficiency through easy, damage-free tightening.
