The Stainless Steel Rivet Nuts under DIN7340 standards are high-performance knurled blind rivet fasteners engineered for adding durable internal threads to thin materials in inaccessible areas. These cylindrical nuts feature a plain finish that highlights the inherent corrosion resistance of stainless steel, available in grades like 304 for everyday use and 316 for extreme conditions such as marine or acidic environments. The knurled outer wall ensures a secure, anti-rotation grip when embedded into sheet metal, hollow tubes, or similar substrates, allowing blind-side installation without backside access. Compliant with DIN7340, they come in metric sizes from M3 to M12, supporting reliable threading for bolts in lightweight assemblies. Ideal for automotive body panels, furniture metal frames, light construction, and electronics enclosures, these stainless steel DIN7340 knurled blind rivet nuts provide vibration-resistant, long-lasting connections that withstand harsh elements. Manufactured by Duojia in Hebei, China, they adhere to ISO9001, ISO14001, and ISO45001 certifications, offering superior hygiene and non-reactivity for food-grade or medical applications. With a production capacity of 10,000 pieces per month, customizable options, and global exports, these plain finish rivet nuts deliver efficient, maintenance-free solutions for professionals needing robust, rust-proof fastening in demanding industrial and general settings, enhancing structural integrity without welding or tapping.
Crafted from premium stainless steel, these DIN7340 knurled blind rivet nuts enable one-sided installation, creating strong threaded inserts in thin or hollow materials where traditional nuts fail. The knurling enhances embedding strength, preventing spin-out under torque, while the plain surface preserves the material’s natural polish and resistance to oxidation, ideal for clean or visible applications. Available in 304 stainless for cost-effective corrosion protection or 316 for superior resistance in saltwater or chemical exposures, they feature internal threads compatible with standard metric bolts. Duojia’s advanced forming and threading processes ensure dimensional accuracy, with SGS certification confirming quality. Installation requires drilling a precise hole, inserting the nut, and expanding it with a rivet tool—manual or pneumatic—for a flush, secure fit. For upkeep, regular cleaning maintains the stainless steel’s integrity, especially in marine or acidic settings, avoiding buildup that could compromise performance. Suited for electronics fastening, automotive mounts, and structural light-duty joins, these rivet nuts reduce assembly time and eliminate backside tools. With minimum orders of 100 pieces, 14-30 day delivery, and packaging in cartons or pallets, they are shipped worldwide, providing versatile, hygienic fastening solutions for industries prioritizing longevity and ease of use.

These Stainless Steel Rivet Nuts boast a knurled exterior that delivers outstanding anti-rotation and embedding strength, ensuring stable threads in thin materials without slippage or loosening over time. The plain finish accentuates the stainless steel’s natural corrosion resistance, making them ideal for hygienic or exposed applications where aesthetics and durability matter. Available in 304 and 316 grades, they offer versatility for general or severe environments, with internal threading that pairs perfectly with metric bolts for secure, repeatable connections. DIN7340 compliance guarantees precision, and the blind installation design streamlines processes in confined spaces, eliminating welding and reducing material stress. Duojia’s customizable options include size adjustments, all rigorously tested for tensile strength and grip. These nuts excel in vibration-prone settings, maintaining hold without additional locking mechanisms, and their non-reactive surface suits food processing or medical equipment. Lightweight yet robust, they support efficient assemblies while minimizing weight, with eco-friendly production aligning with ISO standards. This suite of attributes provides a reliable, low-maintenance fastener that prioritizes hygiene, strength, and ease, delivering value in scenarios demanding long-term performance without compromise.
Stainless Steel Rivet Nuts shine in applications needing corrosion-resistant threading in thin or one-sided access materials across various fields. In automotive sectors, they fasten body panels and interior components, where the knurled grip resists vibrations and stainless steel withstands exposure to elements. Furniture manufacturing uses them for metal frame assemblies, providing clean, strong joints in visible areas without rust concerns. Light construction benefits from their role in structural connections, such as mounting fixtures to hollow profiles or sheet metal in buildings. Electronics enclosures rely on these nuts for secure, non-contaminating threading in sensitive devices. Marine and outdoor equipment leverage 316 stainless for saltwater resistance in boat fittings or signage. Duojia’s products, distributed globally, accommodate custom needs in medical devices for hygienic, durable fixes. With straightforward riveting via tools, they cut installation time, and regular cleaning preserves their integrity in harsh conditions. Their adaptability enhances safety and efficiency, supporting both industrial-scale projects and precise assemblies, from DIY to professional uses, ensuring reliable performance worldwide.
