Blind rivets, also known as pop rivets, are an essential component in many industries, from aerospace and automotive to construction, electronics, and DIY home projects. Their ease of use, strength, and ability to be installed from one side make them especially valuable when access to the reverse side of a joint is limited or impossible.
In this article, we’ll take a comprehensive look at blind rivets—what they are, the different types available, where they’re commonly used, and how to install them properly. Whether you’re a beginner exploring fasteners or a professional seeking deeper insight, this guide will equip you with the knowledge to use blind rivets effectively in your work.
A blind rivet is a type of fastener used to join two or more materials together. Unlike traditional rivets that require access to both sides of a material to set properly, blind rivets can be installed from only one side. This makes them ideal for applications where the back of the joint is inaccessible.
Blind rivets consist of two parts:
The rivet body (also called the shell) – a hollow cylindrical tube with a factory-formed head.
The mandrel – a metal pin inserted into the rivet body that gets pulled through the body during installation.
When installed using a rivet tool (commonly known as a rivet gun), the mandrel is pulled back through the body, expanding it and locking the materials together. Once the mandrel snaps off, what’s left is a clean, tight joint with a domed or flush head on the outer surface.
There are several key advantages that make blind rivets a popular fastening choice:
Single-side access: Can be installed when only one side of the workpiece is reachable.
Quick and simple installation: Requires minimal tools and no complex techniques.
Strong and permanent hold: Ideal for both lightweight and structural applications.
Clean appearance: Rivets offer a smooth, finished look with no protruding screws or nuts.
Vibration-resistant: They stay firmly in place under shaking or vibration, unlike screws that may loosen over time.
Versatile material compatibility: Suitable for metal, plastic, leather, and even fabric.
Blind rivets come in different designs to suit specific needs. Understanding the various types helps you select the right one for your project.
This is the most common type and is typically made of aluminum, steel, or stainless steel. These rivets are used for general applications and offer a solid and reliable joint. They are available in different head styles such as dome, large flange, and countersunk.
These rivets are designed to create a watertight seal. Unlike standard rivets, sealed rivets prevent liquids and gases from passing through the riveted joint, making them ideal for plumbing, HVAC, marine, and electronics applications.
Multi-grip rivets are engineered to work across a wider range of material thicknesses. They reduce the need for exact rivet sizing, making them a good option for maintenance, field repair, or mixed-material assemblies.
Designed for use in soft or brittle materials like plastic, wood, or composites, peel rivets have legs that expand and “peel” back like petals during installation, offering a broad surface grip that prevents damage.
These rivets are typically used in masonry or concrete. The grooves grip the surface of the material firmly, offering excellent resistance against pull-out.
Built for heavy-duty applications, structural rivets have internal locking mechanisms that provide higher shear and tensile strength. They are often used in trucks, trailers, and metal building frames.
Blind rivets are used in countless industries and environments. Here are some of the most common applications:
Automotive: For attaching body panels, interior trims, license plates, and more.
Construction: Used in roofing, siding, ventilation ducts, and window frames.
Aerospace: Selected for their lightweight strength in aircraft assemblies.
Electronics: For fastening lightweight enclosures and components.
Furniture: Commonly used in metal or mixed-material furniture joints.
DIY and Crafts: Great for leather goods, bags, belts, and other personal projects.
Because they are reliable and easy to use, blind rivets are especially valuable for situations where welding or screwing is impractical or undesirable.
Selecting the right blind rivet requires consideration of a few key factors:
Material Compatibility: Use rivets made of the same or compatible material as your workpieces to prevent corrosion. For example, use aluminum rivets for aluminum sheets.
Grip Range: This is the thickness of the materials to be joined. Your rivet must be able to accommodate the total material thickness.
Rivet Diameter: Larger diameters provide greater strength but may require larger holes and more force to install.
Head Style: Choose between dome, countersunk, or large flange depending on the finish you want and the materials being joined.
Environmental Conditions: For outdoor or marine applications, use corrosion-resistant materials like stainless steel or sealed rivets.
Installing blind rivets is straightforward if you follow the proper steps and use the right tools. Here’s a beginner-friendly guide:
Ensure your materials are clean, aligned, and ready to be fastened. Use clamps if necessary to keep them in place.
Use a ruler or template to mark where the rivets will go. Drill holes using a bit that matches the diameter of your rivets. Be sure the holes are clean and burr-free for a snug fit.
Push the rivet through the hole until the head sits flush against the surface. The long mandrel should be sticking out on the accessible side.
Insert the mandrel into the nozzle of your rivet gun. Make sure the gun sits squarely against the rivet head.
Grip the rivet gun handles and begin to squeeze. As you do, the mandrel is pulled through the rivet body, expanding the back end to secure the materials. When enough pressure is applied, the mandrel snaps off with a pop.
Check that the rivet is tight and flush. If the joint feels loose or if the mandrel didn’t snap off properly, remove the rivet by drilling it out and try again.
Choosing the wrong size rivet: Always match the rivet’s grip range and diameter to your materials.
Using incompatible materials: Mixing different metals (like aluminum with steel) can cause galvanic corrosion.
Misaligned holes: Drilling through both materials at once or using a jig helps ensure perfect alignment.
Over-tightening or under-tightening: Follow tool instructions and stop squeezing once the mandrel snaps.
Neglecting safety gear: Always wear eye protection when drilling or using a rivet gun.
A good rivet gun can last for years with minimal maintenance. Clean your tool regularly and keep the moving parts lightly lubricated. If your gun becomes hard to squeeze or stops pulling rivets cleanly, check the jaws and nozzle for wear or debris.
Manual rivet guns are great for small projects, but if you’re doing repetitive or heavy-duty work, consider a pneumatic or cordless rivet tool for greater efficiency.
Blind rivets are a fast, efficient, and professional way to permanently fasten materials together—especially when access to both sides of the joint is not possible. From standard to sealed, multi-grip to structural, there’s a blind rivet to meet nearly every application. With just a few basic tools and a little know-how, anyone can install them with confidence.
