Explore our premium grade extended shank blind rivets and specialized fasteners engineered for extreme grip ranges, high tensile requirements, and severe operating environments.
In modern industrial assembly, standard blind rivets often fail when joining multi-layered structural panels, thick composite materials, or deep-cavity components. Long Shank Rivets (also known as extra-long grip range blind rivets) provide the mechanical reach and radial swelling control necessary to secure heavy-duty joints without compromising clamp load or structural integrity.
As a leading Wholesale Long Shank Rivets Supplier & Factory, WUXI AIPLLE METAL PRODUCTS CO., LTD. engineers extended-reach blind fasteners engineered to bridge thick substrate gaps, eliminate joint vibration fatigue, and accommodate varying material stack-ups. Our automated cold-heading lines manufacture shanks up to 150mm in length, maintaining strict tolerances across diameter ratios and mandrel retention zones.
Precision execution in extended shank riveting requires exact alignment of mandrel break loads, material elongation, and protective finishings. Below is our standardized performance benchmark for industrial B2B procurement:
| Rivet Type | Material Combination | Diameter Range (mm) | Shank Length Range (mm) | Grip Range (mm) | Shear / Tensile Rating | Corrosion Resistance |
|---|---|---|---|---|---|---|
| Extra Long Open End | Aluminium 5052 Body / Steel Mandrel | 3.2mm - 6.4mm (1/8" - 1/4") | 25mm - 120mm | 18mm - 105mm | Standard to Medium | Salt Spray 48h - 240h |
| Long Shank Closed End | 304 / 316 Stainless Steel Body & Mandrel | 4.0mm - 6.4mm | 20mm - 80mm | 12mm - 68mm | High Structural Shear | Salt Spray 1000h+ (V4A) |
| Extra Long Multi-Grip | Zinc Plated Carbon Steel | 4.8mm - 6.4mm | 30mm - 100mm | 15mm - 85mm (Adaptive) | High Pull-Out Strength | Electro-Galvanized 96h+ |
| Structural Interlock / Monobolt | Structural Carbon Steel / Stainless | 6.4mm - 9.8mm | 35mm - 150mm | 20mm - 130mm | Ultra Heavy Industrial Load | Geomet / Zinc-Nickel Plating |
| Tri-Fold / Lantern Long Shank | High Modulus Aluminium Alloy | 4.0mm - 7.7mm | 25mm - 90mm | 10mm - 75mm | Clamping Soft Materials | Anodized / Powder Coated |
As industrial manufacturing migrates toward lightweight alloys, ultra-high-strength steels (UHSS), and multi-material composite sandwich panels, long shank riveting technology is undergoing major technological evolution:
Transitioning from basic Al 1050/3003 alloys to high-magnesium 5056 and 6061-T6 aluminum formulas. This shift delivers 35% higher shear yield stresses while reducing overall joint mass in electric vehicles (EVs) and aerospace structural frames.
Developing engineered grooves along extended rivet shanks. This design enables a single long shank rivet length to clamp across wide variance in stack thickness, reducing assembly line component SKU counts by up to 60%.
Integrating synthetic rubber (EPDM/HNBR) under-head seals and internal closed-end mandrels on long shanks to guarantee IP68 waterproof ratings for subsea infrastructure and high-voltage battery housing units.
Due to their mechanical stability across heavy material stacks, our long shank rivets are deployed across demanding global industries:
Used extensively in EV battery tray construction, composite-to-aluminum space frames, and commercial bus chassis bodywork. Extended shanks effortlessly pierce through insulating foam layers, composite structural panels, and metallic stiffeners to ensure high clamp loads.
Outdoor renewable energy infrastructure demands long-term vibration resistance against wind load and thermal expansion. Our long shank structural steel rivets hold solar tracker frames, ballast brackets, and wind turbine internal cable ducts tightly intact over 25+ years.
Thick insulated polyurethane sandwich panels used in industrial cold storage facilities and air-handling units require extra-long blind rivets that expand symmetrically without crushing fragile inner foam cores.
Heavy exterior aluminum composite cladding panels (ACP) installed over deep sub-frame steel studs require high-shear long shank fasteners certified for dynamic seismic loads and weatherproofing.
WUXI AIPLLE METAL PRODUCTS CO., LTD. operates as a technology-driven manufacturing engine located in Wuxi, China. Specialized in blind rivets, rivet nuts, and custom non-standard industrial fasteners, our operations adhere strictly to the IATF 16949:2016 automotive standard and ISO 9001 quality framework.
Multi-station high-speed cold heading machinery capable of forming shank lengths up to 150mm with dimensional tolerances within ±0.05mm.
100% automated optical sorting systems check shank concentricity, head height, and mandrel retention to eliminate defect risk before shipment.
In-house metallurgical testing, salt-spray corrosion chambers, tensile stress testing, and finite element analysis (FEA) for non-standard customer tooling.
We strictly control every phase of manufacturing to guarantee that every long shank rivet batch functions reliably on automated riveting lines:
Sourcing premium grade aluminum alloy wire (5052, 5056, 5005), 304/316 stainless steel, and high-carbon steel wire rods. Spectrographic analysis verifies chemical composition prior to cold drawing.
Multi-stage cold heading machines shape the head style (Dome, Countersunk, Large Flange) and extend the rivet body shank length while maintaining precise internal mandrel entry chamfers.
Mandrel wires undergo precise head forming, knurling, and notch shearing to control break load points. High-speed automated assembly machines combine the rivet body and mandrel seamlessly.
In-process dimensional measurement, shear/tensile pull testing, head retention testing, and optical sorting ensure strict export quality standards (DIN 7337, ISO 15977).
Rivet products are packed into customized inner boxes and heavy-duty corrugated export cartons, automatedly weighed to prevent piece count errors, palletized, and prepared for air/sea freight logistics.
Serving over 200 international clients in more than 50 countries, WUXI AIPLLE METAL PRODUCTS CO., LTD. provides flexible procurement solutions designed for global distributors, tier-1 automotive suppliers, and industrial OEMs.
We tailor shank lengths, flange head diameters, painted surface colors (RAL palette), and custom brand packaging to match your precise brand requirements and technical drawings.
All materials are 100% compliant with RoHS 3.0, REACH, and Conflict-Free Minerals directives. Full material test reports (MTR) and PPAP Level 3 documentation are available upon request.
Located near major deep-water ports (Shanghai and Ningbo), we offer agile lead times (15-25 days standard production) with flexible FOB, CIF, DDP, and DAP incoterms.
Our complete product range includes open end blind rivets, multi-grip series, structural hemlock rivets, lantern tri-fold blind rivets, and knurled rivet insert nuts:
Standard & extended long shank blind rivets for high-speed metal sheet joining.
Adaptive grip ranges accommodating variable work-piece thickness seamlessly.
High shear strength fasteners for heavy machinery and vehicle frames.
Large tail spread expansion for soft, brittle, or composite sheet materials.
Strong internal threads created in thin metal plates without back-side access.
Specialized nickel-zinc plated expansion nuts and custom cold headed parts.
A long shank rivet features an extended body length (typically exceeding 25mm up to 150mm) and a corresponding long mandrel. This allows design engineers to join thick material stacks, sandwich composites, or deep sub-assemblies where standard grip lengths fall short of forming a proper bulb head on the blind side.
The total thickness of all combined materials to be joined (stack height) must fall squarely within the rivet's specified "Grip Range." Selecting a long shank rivet with too short a grip will prevent the blind head from setting; a grip range that is too long will cause loose joints and insufficient pull-down force.
Yes. Our heavy-duty and structural long shank rivets incorporate mechanical mandrel locking mechanisms (such as structural Interlock or Monobolt designs). The mandrel core is locked inside the rivet sleeve post-setting, resisting structural shear forces and severe operational vibrations.
Absolutely. WUXI AIPLLE operates an experienced R&D engineering department capable of tooling custom cold-heading dies. We produce non-standard shank lengths, oversized flange heads, and special head geometries according to customer CAD/ISO specifications.
Depending on environmental conditions, we supply long shank rivets in 304/316 stainless steel, anodized 5052/5056 aluminum, electro-zinc plated carbon steel, and Geomet/Dacromet finishes. We also offer colored organic powder coatings matched to RAL color codes for architectural applications.
