A Complete Guide to Blind Rivet Installation and Applications
What is a Blind Rivet?
A blind rivet is a one-time-use fastener composed of a rivet body (sleeve) and an inner mandrel (usually made of carbon steel or aluminum). It allows for secure fastening even when only one side of the material is accessible.
How It Works & Installation Steps
Operating Principle
Insert the sleeve into pre-drilled holes between materials.
Pull the inner mandrel using a manual, pneumatic, or battery-powered rivet gun.
Deformation occurs as the mandrel head expands the sleeve into a "barrel shape."
Fixing completed when the mandrel breaks off under pre-set tension.
Installation Example: Sealed-Type Blind Rivet
Load the rivet into the tool nozzle.
Insert fully into the hole; press tool flush to the material.
Activate the trigger; the rear of the sleeve forms a sealing deformation.
Mandrel snaps when force is reached—installation complete.
Common Types of Blind Rivets
| Type | Features | Common Applications |
|---|---|---|
| Standard Aluminum/Iron | Lightweight, corrosion-resistant, wide grip range | Aluminum frames, automotive, cases |
| Sealed-Type | Withstands pressure (up to 300 bar), water/airproof | Gas lines, HVAC, vibration-prone assemblies |
| Multi-Grip/Folding | Expands in versatile shapes, adapts to various thicknesses | Motorcycles, electronics, lighting |
| Pull-Thru | No mandrel remnants, clean finish | High-precision equipment, aesthetic projects |
Tools Overview
Manual Rivet Gun: Best for small batches or on-site repair.
Pneumatic/Battery Gun: Great for high-volume, consistent installations.
Automated Systems: Integrated into assembly lines for mass production.
Key Advantages
Single-side installation: Ideal for blind holes or inaccessible back sides.
Firm, anti-loosening: Once installed, cannot be removed without damage.
Stock efficiency: One rivet covers a range of thicknesses.
Cost-effective: Simpler and cheaper than bolts and nuts.
Corrosion resistance: Aluminum/stainless steel options available.
Common Applications
Automotive & Motorcycles: Body panels, interiors.
Construction: Windows, curtain walls, waterproof joints.
Home Appliances: Casings, metal housings.
Piping Systems: Pressure-tight joints.
Aerospace & Transport: Vibration and corrosion-resistant structures.
Summary
Blind rivets are a reliable, one-time fastening solution offering fast, secure, and tamper-proof connections. Whether you need standard, multi-grip, sealed, or aesthetic rivets, there's a solution for your specific application. Choose the right rivet type and tool to ensure efficient and durable assembly results.
