High-strength blind riveting and threaded insert solutions manufactured under rigorous IATF 16949 quality protocols.
At WUXI AIPLLE METAL PRODUCTS CO., LTD., we specialize in high-precision engineered blind rivets, rivet nuts, and customized non-standard industrial fasteners. Operating with full ISO 9001:2015 and automotive-grade IATF 16949:2016 quality control standards, our production infrastructure is built to eliminate mechanical defects, guarantee uniform thread engagement, and deliver uncompromising structural safety across heavy-duty assembly lines.
Driven by an advanced R&D engineering group, WUXI AIPLLE introduces over 10 technical innovations annually. Our commitment extends beyond simple manufacturing—we engineer optimized joint solutions that resolve difficult single-sided access challenges, maximize shear strength, and protect against severe vibration-induced loosening in automotive, aerospace, and marine systems.
Choosing the correct stainless steel grade is paramount for structural reliability, load longevity, and preventing galvanic failure in harsh operational environments.
Composed of 18% Chromium and 8% Nickel, AISI 304 offers exemplary tensile performance and excellent resistance to atmospheric oxidation. Ideal for general industrial machinery, automotive sub-frames, HVAC enclosures, and indoor commercial equipment.
Enhanced with 2-3% Molybdenum, AISI 316 delivers superior resistance against chloride pitting, chemical solvents, and marine salt-spray. It is specified for offshore energy structures, chemical processing plants, and coastal infrastructure.
For extreme spin-out prevention in thin sheet metal, our Full Hexagonal and Half-Hexagonal Stainless Steel Rivet Nuts deliver up to 250% higher spin-out torque resistance compared to conventional smooth cylindrical body designs.

Our engineering team designs custom structural joints for specialized global sectors, tackling high dynamic stress, thermal expansion, and aggressive environmental exposure.
As automakers transition to thin-gauge aluminum alloys and composite materials, traditional thermal welding becomes unfeasible. WUXI AIPLLE stainless steel rivet nuts supply high-strength load-bearing threads in ultra-thin EV battery enclosures, door frames, and chassis brackets without altering material metallurgy.
Outdoor photovoltaic racking and wind turbine control cabinets face continuous vibration and environmental weathering. Our closed-end SS316 rivet nuts guarantee hermetic sealing against moisture ingress while providing dependable thread security under severe aerodynamic loads.
High-speed trains and aircraft interior paneling require fasteners certified to strict shear force and tensile fatigue limits. Our cold-formed structural fasteners absorb extreme dynamic forces, ensuring structural stability across long service lifecycles.
Leveraging automated multi-station cold heading, optical sorting technologies, and lean smart logistics to ensure competitive wholesale pricing and bulletproof production stability.
Our factory floor is equipped with high-speed multi-station cold forming machines capable of extruding high-grade stainless steel wire into precise rivet nut blanks without material fracture. Cold working enhances grain alignment within the fastener body, significantly boosting ultimate tensile capacity compared to traditional machining processes.
To meet strict automotive assembly standards, every batch passes through automated 360-degree optical sorting machines. Dimensions including thread pitch, head thickness, overall length, and wall uniformity are measured at high speeds, guaranteeing zero defect delivery for automated robotic installation lines.
From raw material wire rod inspection to automated post-weighing packaging, our end-to-end process guarantees complete lot traceability.
Chemical analysis & tensile verification of incoming SS304/SS316 wire coils.
Multi-station cold heading forming head profile, knurling, and body chamber.
Automated thread tapping guaranteeing 6H metric or 2B unified thread tolerances.
Chemical passivation bath to maximize corrosion resistance & remove free iron particles.
Automated CCD camera inspection filtering out dimensional anomalies.
Post-weighing box packaging with detailed lot code tagging for full traceability.
We lower Total Cost of Ownership (TCO) for global distributors, Tier-1 OEM integrators, and industrial procurement officers through flexible manufacturing terms and technical support.
Streamline your supply chain. We provide customized buffer stocking and scheduled releases to eliminate inventory stockouts and optimize working capital usage.
Full material compliance transparency. Every shipment includes EN 10204 3.1 chemical composition, hardness testing, tensile strength, and salt spray test certificates.
Need non-standard flange dimensions, extra-long body grip ranges, or specialized surface coatings? Our engineering unit turns custom CAD models into production samples within 15 days.
Leading the next generation of blind structural joining technology through intelligent design, lightweight alloy R&D, and green zero-carbon production initiatives.
WUXI AIPLLE is developing smart rivet nut prototypes with integrated micro-piezoelectric sensors. Designed for critical aerospace and structural infrastructure joints, these smart fasteners monitor clamp load loss, bolt loosening torque, and structural vibration in real-time via wireless IoT protocols.
Stainless steel threads are prone to friction-induced galling during automated high-speed power driving. Our R&D team is expanding dry-film lubrication coatings and nanostructured surface treatments that eliminate thread cold-welding without requiring messy external oils or pastes.
Our products comply with major international fastener standards, ensuring seamless installation across diverse global engineering platforms.
Full adherence to DIN 7337, ISO 15977, ISO 15978, and ISO 14588 dimensional specs.
