Multi-grip structural rivets are engineered fastening solutions designed to perform reliably across varying material thicknesses. You use them when strength, vibration resistance, and installation efficiency matter more than tight tolerance stacking. Unlike standard blind rivets, multi-grip structural rivets deliver consistent clamp force, even when hole sizes or material stacks vary.
This article explains how multi-grip structural rivets work, why you should choose them, where you can apply them, and how you can install them correctly. You will also review real-world case studies and practical guidance backed by industry practice from Avlock International India.
Multi-grip structural rivets are high-strength blind fasteners that accommodate a wide grip range with one rivet size. You can fasten multiple material thickness combinations without changing rivet length. This capability reduces inventory, simplifies installation, and lowers assembly errors.
Unlike conventional blind rivets, multi-grip structural rivets form a controlled bulbed tail on the blind side. This tail provides high shear strength, tensile strength, and vibration resistance. The mandrel locks inside the rivet body, adding structural integrity.
You typically use multi-grip structural rivets when welding is impractical or when you need one-sided access.
Multi-grip structural rivets expand differently from standard rivets. When you pull the mandrel, the rivet body deforms progressively instead of collapsing at one point. This controlled deformation allows the rivet to fill oversized holes and uneven stacks.
Key working principles include:
This mechanism is why multi-grip structural rivets perform well in structural applications.
You can cover multiple material thicknesses using one rivet size. Multi-grip structural rivets reduce SKU count and storage costs. This advantage matters in large-scale manufacturing.
Multi-grip structural rivets deliver excellent shear and tensile strength. You can rely on them in load-bearing assemblies without secondary fasteners.
The locked mandrel prevents loosening under vibration. Multi-grip structural rivets are suitable for transport, machinery, and dynamic loads.
You only need access from one side. This feature makes multi-grip structural rivets ideal for hollow sections and closed profiles.
Even with hole variation, multi-grip structural rivets maintain joint integrity. You reduce rework and inspection failures.

If your application demands reliability, this rivets outperform standard blind rivets.
You can source multi-grip structural rivets in several material combinations:
Your choice depends on corrosion resistance, load requirements, and environmental exposure. Avlock International India offers multiple material options tailored to industrial needs.
You use multi-grip structural rivets for body panels, frames, brackets, and interior assemblies. Their vibration resistance supports long-term durability.
Multi-grip structural rivets secure metal cladding, façades, handrails, and support frames. You benefit from fast installation and consistent performance.
Railway coaches rely on multi-grip structural rivets for structural panels and fittings. One-sided installation simplifies assembly.
You install multi-grip structural rivets in solar mounting systems and wind turbine components where access is limited.
Machine housings, enclosures, and support frames depend on multi-grip structural rivets for long service life.
Choose diameter based on load requirements, not just hole size. Multi-grip structural rivets perform best when sized correctly.
Drill clean, burr-free holes. Poor hole quality reduces joint strength, even with multi-grip structural rivets.
Always use a calibrated rivet gun compatible with structural rivets. Insufficient pull force causes incomplete mandrel locking.
After installation, ensure the mandrel is locked inside the rivet body. This confirms full structural performance.
Do not exceed the recommended pull force. Over-clamping can deform thin materials.
Multi-grip structural rivets typically comply with international fastening standards. You should verify conformity with ISO, DIN, or customer-specific requirements. Avlock International India follows strict quality control and traceability protocols.
