Engineered for vibration-prone environments, thin sheet metal joining, multi-thickness clamping, and high structural load assemblies across global manufacturing sectors.
As modern engineering transitions toward lightweight composite materials, mixed-metal assemblies, and automated high-speed production lines, traditional single-grip blind rivets face significant technical bottlenecks. Multi-Grip pop rivets represent a vital technological evolution in blind fastening science.
Standard blind rivets demand explicit grip length matching for every fractional millimeter change in material stack thickness. Multi-Grip rivets feature an expanded working range, allowing one Multi-Grip fastener to replace up to three standard rivet sizes. This drastically lowers inventory holding costs and eliminates operator sizing errors on assembly lines.
In dynamic applications such as electric vehicle (EV) chassis panels, heavy transport HVAC, and railway interiors, structural joint vibration causes standard rivets to loosen. AIPLLE Multi-Grip rivets utilize a controlled radial expansion mechanism that expands into oversized or misaligned holes while mechanically locking the mandrel stem inside the sleeve.
When driven, the Multi-Grip body deforms outward to create a broad, flat tail configuration against the blind side. This uniform clamping pressure ensures weather-tight seal integrity against liquid and dust ingress, mitigating galvanic corrosion risk when joining dissimilar metals.
At WUXI AIPLLE METAL PRODUCTS CO., LTD., our Multi-Grip blind rivets are manufactured through multi-station precision cold-heading systems using high-grade structural alloys. Here is the technical breakdown of our metallurgical standards and stress distribution performance.
| Rivet Material Combination | Body Material Standard | Mandrel Material Standard | Shear Load Range (kN) | Tensile Load Range (kN) | Corrosion Resistance (Salt Spray) |
|---|---|---|---|---|---|
| Aluminium / Steel | AA 5052 / AA 5056 Polished | Carbon Steel Zinc Plated (Class 8.8) | 1.10 - 2.85 kN | 1.40 - 3.60 kN | 48 Hours NSS (Zinc Clear Passivation) |
| Steel / Steel (Full Carbon Steel) | Cold Heading Q195 / Q235 Steel | High Tensile Boron Steel Mandrel | 2.40 - 5.80 kN | 3.10 - 7.20 kN | 480 - 720 Hours NSS (Cr3+ Electro-Galvanized) |
| Stainless Steel / Stainless Steel | AISI 304 / AISI 316 Stainless | AISI 304 Stainless Steel Mandrel | 3.80 - 8.50 kN | 4.50 - 9.80 kN | 1000+ Hours NSS (Passivated Surface) |
| Aluminium / Stainless Steel | AA 5052 Anodized / Painted Body | AISI 304 Stainless Steel Mandrel | 1.30 - 3.10 kN | 1.60 - 4.10 kN | 720 Hours NSS (Marine & Solar Grade) |
During installation, as the setting tool pulls the mandrel head through the rivet body, the Multi-Grip design forces the sleeve to expand outwards into a series of broad bulbs. This distributes clamping force over a wider surface area on the blind side, preventing pull-through on fragile, thin, or soft materials like sheet aluminum, plastics, and fiberglass composite panels.
Unlike basic pop rivets where the broken mandrel stem can drop out and cause rattling or electrical short circuits, AIPLLE Multi-Grip fasteners mechanically crimp and lock the retained mandrel head inside the rivet shell. This creates a solid structural core resistant to high shear forces and fluid penetration.
Hole preparation in high-speed manufacturing often results in slight diameter variance or misalignment between joined sheets. The flexible body geometry of our Multi-Grip rivets expands radially to completely fill burred, ovalized, or slightly oversized pre-drilled holes up to +0.4mm above nominal shank diameter.
