Engineered for extreme structural loads, high torque resistance, and corrosion-heavy industrial applications worldwide.
In modern mechanical engineering and light-weight structural assembly, the demand for high-strength, single-sided mechanical joinery has surged exponentially. Known in Spanish-speaking markets and international supply chains as Tuerca Remachable (blind rivet nuts or threaded inserts), these precision components provide permanent, load-bearing internal threads in thin-walled materials where tapped threads are technically unfeasible or cost-prohibitive.
As a premier Chinese manufacturer headquartered in the industrial hub of Wuxi, WUXI AIPLLE METAL PRODUCTS CO., LTD. has redefined the benchmark for cold-formed blind fasteners. By integrating advanced metallurgy, cold-heading precision, automated optical sorting, and strict automotive-grade compliance (IATF 16949:2016), our facility bridges the critical gap between high-volume manufacturing cost-efficiency and zero-defect industrial reliability.
WUXI AIPLLE METAL PRODUCTS CO., LTD. has specialized in blind rivets, rivet nuts (Tuercas Remachables), and non-standard custom fasteners for over two decades. Our company was founded on a singular engineering principle: eliminating defect-induced downtime for structural fabricators and global OEMs.
Our ISO9001-compliant quality control system rigorously eliminates dimensional variations, guarantees thread pitch consistency, and protects your brand from costly assembly line delays or field recalls. With our specialized IATF 16949-2016 Quality Management System for automotive fastener production, we deliver structural fasteners engineered to withstand extreme vibration, thermal expansion, and mechanical shear.
Powered by an experienced R&D engineering group, WUXI AIPLLE delivers more than 10 annual innovations to address emerging market demands—such as ultra-lightweight EV chassis joining, marine-grade anti-corrosion fasteners, and high-torque full hex rivet inserts. Our dedicated international technical support team responds instantly to ensure your global supply chain operates seamlessly.
Selecting the optimal blind rivet nut requires a rigorous analysis of parent sheet material, tensile load requirements, torque-to-yield expectations, and environmental exposure. The table below outlines the core technical metrics across our main manufacturing lines:
| Fastener Type | Material Grade | Standard Specifications | Thread Range | Corrosion Resistance (Salt Spray) | Primary Application |
|---|---|---|---|---|---|
| Full Hex Body Tuerca Remachable | Carbon Steel 10B21 / Nickel Alloy | DIN 7337 / ISO 15977 | M4 – M12 | Zinc-Nickel Plated (720h - 1000h) | Automotive Chassis & Heavy Machinery |
| Knurled Round Body Rivet Nut | Stainless Steel 304 / 316 | IFI-114 / OEM Standard | M3 – M10 | Pure Passivated (>1000h Marine Grade) | Solar Arrays, HVAC & Marine Fabrication |
| Flat / Countersunk Head Insert | Aluminium 5052 / 5056 Grade | Custom Non-Standard / ISO | M3 – M12 | Anodized / Natural (>240h) | Aerospace Cabinets & Lightweight Electronics |
| Tri-Fold / Lantern Blind Rivet | Aluminum Alloy Body + Steel Core | High-Grip Structural Standard | 4.8mm – 6.4mm | Powder Coated / Painted (>500h) | Plastics, Fiberglass & Soft Sheet Metals |
| Structural Monobolt / Hemlock | High-Tensile Carbon Steel / Stainless | Structural Mechanical Interlock | 4.8mm – 6.4mm | Yellow/Clear Zinc Plated (>480h) | Commercial Vehicles, Rail & Bridge Racking |
From raw wire coil selection to 100% automated optical sorting, our production roadmap guarantees operational consistency.
We source ultra-pure wire coils including polished 5052 aluminum, zinc-plated carbon steel 10B21, and 304/316 stainless steel. Spheroidize annealing ensures optimal grain flow during heavy cold heading.
Utilizing high-speed Italian and Taiwanese multi-station cold formers, the blind body and head flange (dome, flat, or countersunk) are forged with extreme dimensional accuracy (±0.02mm tolerances).
Internal threads (M3 to M12) are precision-tapped using automated CNC tapping heads. Threads are inspected for pitch accuracy, zero burrs, and high torque resistance to eliminate thread stripping.
Automatic assembly machinery joins the rivet body with precision-machined mandrels (for blind rivets), maintaining tight concentricity and uniform break-load points.
100% optical laser sorting machines screen every single manufactured Tuerca Remachable for thread depth, body diameter, head height, and surface flaws—targeting < 10 PPM defect rates.
Products are carefully sorted, post-weighed, sealed in moisture-proof inner boxes, and stacked in reinforced export cartons on fumigated pallets for global ocean or air transit.
We operate state-of-the-art cold forming machines, universal mechanical testing rigs, salt-spray corrosion chambers, optical sorting machines, and high-speed automatic assemblers.
Tuerca Remachable components are critical across key international growth sectors—joining thin metals, plastics, and composites when back-side access is impossible.
Tuercas Remachables (especially Full Hex and Expansion Nuts) are widely used in EV battery enclosures, aluminum structural frames, and interior trim panels. They provide high spin-out resistance under severe vehicle vibration.
Stainless steel closed-end rivet nuts and tri-fold lantern rivets are deployed in utility-scale solar tracker mounts and inverter enclosures, delivering waterproof, corrosion-proof performance in harsh desert and marine environments.
Knurled round body rivet nuts ensure flush mounting in server racks, sheet metal control cabinets, and commercial air conditioning units, offering effortless disassembly for maintenance without stripping threads.
China’s Yangtze River Delta, particularly Wuxi, represents the highest concentration of cold-heading engineering expertise worldwide. Sourcing directly from WUXI AIPLLE METAL PRODUCTS CO., LTD. offers distinct commercial advantages:

Full Hex body rivet nuts require a hex hole punch. They completely eliminate body spinning (spin-out) under high installation torque, making them ideal for high-vibration automotive chassis and heavy equipment. Round body knurled rivet nuts fit standard drilled holes, offering excellent grip in sheet metal where hex punching is not available.
Grip range represents the total combined thickness of the sheets being fastened. To ensure a solid rear-side bulb upset without thread distortion, the combined panel thickness must fall strictly within the manufacturer’s specified min/max grip range (e.g., 0.5mm – 3.0mm).
Open-end rivet nuts allow long bolts to pass completely through the fastener body, offering maximum versatility. Closed-end (sealed) rivet nuts feature a solid blind end that prevents fluid, dust, and moisture ingress, making them mandatory for solar enclosures, marine hulls, and automotive exterior bodies.
WUXI AIPLLE operates under strict ISO 9001:2015 and IATF 16949:2016 management standards. All raw materials undergo mill test certifications (MTC), and our finished fasteners comply with RoHS, REACH, DIN 7337, and IFI industrial standards.
