The DIN7340 Knurled Rivet Nuts with galvanized zinc plating are robust cylindrical fasteners designed for creating strong internal threads in thin materials without requiring backside access. These blind rivet nuts feature a knurled outer surface that enhances grip and prevents rotation during installation, making them ideal for sheet metal, square tubes, and other lightweight structures. Crafted from durable carbon steel in grades like 4.8, 8.8, up to 12.9, or stainless steel variants for added corrosion resistance, the zinc plating provides a protective layer against rust, ensuring longevity in various environments. Compliant with DIN7340 standards, they come in metric sizes from M3 to M12, supporting easy blind riveting with manual or electric tools. Perfect for applications in automotive mounts, furniture assembly, and construction, these galvanized zinc plated DIN7340 knurled rivet nuts offer reliable performance by embedding securely into workpieces, eliminating the need for welding or tapping. Manufactured by Duojia in Hebei, China, they meet ISO9001, ISO14001, and ISO45001 certifications, with a supply capacity of 10,000 pieces per month and customizable options for bulk orders. Whether for heavy industry or general use, these rivet nuts deliver cost-effective, vibration-resistant threading solutions that enhance assembly efficiency and structural integrity.
These galvanized zinc plated DIN7340 knurled rivet nuts are engineered for blind installation, allowing users to add threaded inserts to materials where only one side is accessible. The knurling on the exterior ensures a firm hold by biting into the workpiece during riveting, while the internal threads accommodate standard bolts for secure connections. Available in carbon steel for everyday strength or stainless steel for environments prone to moisture or chemicals, the zinc galvanization forms a uniform barrier that resists oxidation and improves durability. Sizes range from nominal diameters of 3mm to 10mm, with precise dimensions ensuring compatibility with drilled holes. Duojia’s production process includes cold pressing and stamping for consistency, backed by SGS certification and quality inspections. Installation is straightforward: drill a matching hole, insert the nut, and use a riveting tool to expand and lock it in place—no specialized backside tools needed. For maintenance, inspect the zinc coating for wear and apply anti-rust treatments if scratches occur to prevent corrosion. Ideal for automotive license plate fixtures, metal furniture frames, and light structural joins, these rivet nuts support minimum orders of 100 pieces with 14-30 day delivery, packaged in cartons or pallets for global shipment to markets like Europe and Asia.

Distinguished by their knurled design, these DIN7340 rivet nuts provide exceptional anti-rotation grip, embedding firmly into thin materials to create stable threaded points without slippage. The galvanized zinc plating adds a layer of rust resistance, making them suitable for both indoor and outdoor use, while stainless steel options enhance performance in corrosive settings like marine or chemical applications. Compliant with DIN7340, they offer precise metric threading for seamless bolt integration, with carbon steel grades ensuring high tensile strength for demanding loads. The blind riveting capability simplifies installation in hard-to-reach areas, reducing labor time and eliminating welding needs. Duojia’s customizable features include size variations and coating thickness, all verified through hardness and zinc tests for reliability. Their compact cylindrical form minimizes material stress, and the plating maintains integrity under abrasion or exposure. Versatile for lightweight assemblies, these nuts resist vibration effectively, supporting repeated use without degradation. Eco-friendly production processes align with ISO standards, and the design’s efficiency cuts down on additional fasteners, offering cost savings. Overall, these features combine to deliver a durable, user-friendly solution for creating strong, threaded connections in thin-walled structures, prioritizing ease and longevity.
DIN7340 Knurled Rivet Nuts with galvanized zinc plating excel in applications requiring secure threading in thin or inaccessible materials across industries. In automotive manufacturing, they mount license plates, interior panels, and lightweight frames, where the knurling ensures vibration-resistant holds during vehicle operation. Furniture assembly benefits from their use in metal frames and cabinets, providing strong joints without damaging delicate surfaces. Construction sectors apply them for light-duty structural connections, such as attaching fixtures to sheet metal or hollow sections in buildings. Electronics and appliance production utilize these nuts for embedding threads in enclosures, leveraging the zinc plating for corrosion protection in humid environments. In general industry, they support pipeline fittings and equipment housings, enabling quick blind installations. Duojia’s products, exported to regions like Russia and Australia, accommodate custom needs in marine accessories for rust-free performance. With simple tool-based riveting and easy coating repairs, they minimize downtime, enhancing efficiency in both heavy and light applications, from DIY projects to professional builds, ensuring reliable, long-lasting threaded solutions.
