Blind Rivets

Blind Rivets

Blind rivets are two-piece assemblies consisting of the rivet body and the accompanying setting mandrel. Another common name for blind rivets is "Pop Rivet". Pop rivets were the original brand name created to describe the popping sound that is made when a blind rivet is set. The advantage of using a blind rivet is because they can be installed from the front side of the application where access to the back side or blind side is not available or necessary.

Understanding Blind Rivets

Blind rivets consist of two main components: a tubular body and a mandrel. During installation, the rivet is inserted into a pre-drilled hole, and a specialized rivet tool is used to pull the mandrel. This action causes the rivet body to expand, forming a secure and permanent joint. The ability to fasten from one side, known as “blind fastening,” is what makes these rivets uniquely suited for applications with restricted access.

Blind rivets offer several key benefits:

  • Strong, Permanent Joints: Blind rivets create robust connections capable of withstanding vibration, pressure, and environmental factors.
  • Minimal Tool Requirements: Only a rivet tool is needed for installation, simplifying the fastening process.
  • Versatility Across Industries: Blind rivets are suitable for joining materials like metal, plastic, wood, and more.

Types of Blind Rivets

Blind rivets are available in a wide range of types to accommodate specific application needs. Each type offers distinct advantages, making it crucial to select the right rivet for optimal performance and durability.

  • Open-End Blind Rivets: The most common and cost-effective type, ideal for general-purpose fastening.
  • Closed-End Blind Rivets: Also referred to as sealed blind rivets, these are designed to create a watertight seal, preventing the passage of liquids or gases.
  • Multi-Grip Rivets: Engineered for a wider grip range, multi-grip rivets reduce the need for multiple rivet sizes and improve inventory efficiency.
  • Structural Blind Rivets: Built for high-strength applications, structural rivets provide superior shear and tensile strength, making them suitable for demanding environments.
  • Countersunk Blind Rivets: Featuring a flush head design, countersunk rivets deliver a smooth, professional finish ideal for applications requiring a sleek appearance.

Materials and Sizes

Blind rivets are manufactured in a variety of materials and sizes to meet specific environmental and application requirements. Selecting the appropriate material ensures resistance to factors like corrosion, heat, and stress, while the correct size guarantees a secure and reliable joint.

  • Materials: Aluminum, stainless steel, Monel, and plastic are popular choices. Each material offers unique properties to suit different environments.
  • Sizes: Blind rivets come in a range of diameters and lengths, from lightweight options for small projects to heavy-duty sizes for industrial applications.

By carefully selecting the material and size, professionals can achieve optimal performance and durability in their fastening solutions.

Applications of Blind Rivets

The versatility and reliability of blind rivets make them a go-to fastening solution in countless industries. Their ability to securely join materials without requiring access to both sides of the assembly makes them indispensable in challenging environments.

  • Aerospace: Frequently used in aircraft manufacturing and repair due to their high strength-to-weight ratio and resistance to vibration.
  • Automotive: Ideal for assembling vehicle components, particularly in areas where access is restricted, such as body panels and interior systems.
  • Construction: Commonly employed to securely join materials in structural applications, roofing, and HVAC systems.
  • Electronics: Used to fasten delicate components in electronic devices with precision and reliability.
  • Marine: Closed-end blind rivets are often used in marine applications for their watertight sealing properties and corrosion resistance.

Advantages of Blind Rivets

Blind rivets offer several unique advantages that make them a preferred choice for many industries. They streamline the fastening process while delivering consistent, high-quality results.

  • Cost-Effective: Blind rivets offer a competitive edge with lower material costs compared to threaded fasteners. Their simplified installation process further reduces labor expenses.
  • Lightweight Design: Aluminum blind rivets are ideal for applications where weight reduction is critical, such as aerospace and HVAC systems.
  • Reliable Performance: Designed with pre-set breaking points, blind rivets ensure consistent installation pressure, minimizing the risk of over-torquing or loosening.
  • Vibration Resistance: Properly installed blind rivets maintain their hold, even in environments with significant vibration, outperforming many traditional fasteners.
  • Efficient Assembly: Capable of handling high-speed installations, blind rivets enable productivity rates of 150–500 fastenings per hour in industrial settings.
  • Clean Aesthetics: With no wrench marks or dimpling, blind rivets provide a polished finish, making them suitable for applications requiring a seamless appearance.
  • Exceptional Versatility: Blind rivets are available in configurations suitable for joining heavy structural components, delicate plastics, and everything in between.
  • Tamper Resistance: Countersunk blind rivets sit flush with the surface, offering a tamper-resistant fastening solution with an added layer of security.
  • Variety of Types: From tubular and solid to split and blind rivets, there’s a rivet type for every fastening need, ensuring adaptability for any project.

Blind Rivets vs. Pop Rivets

Blind rivets and pop rivets are often used interchangeably, but they have an interesting history. In 1934, the George Tucker Eyelet Company developed a revolutionary fastener for aircraft manufacturers that could be installed from one side of the material. The rivet’s installation made a distinctive “popping” sound, which inspired the name POP® rivets—a term that later became a registered trademark.

Today, "pop rivet" is commonly used as a generic term for blind rivets, much like how "Velcro®" refers to hook-and-loop fasteners. Regardless of the name, blind rivets remain a versatile and reliable choice for securing materials when access is limited to one side.

FAQs About Blind Rivets

Understanding the basics of blind rivets can help you select the right fasteners for your needs. Below, we answer common questions about blind rivets, their uses, and how to install them effectively.

What is a blind rivet?

A blind rivet is a fastener used to join materials when access is available from only one side. It consists of a tubular body and a mandrel; during installation, the mandrel is pulled through the body to expand it, forming a secure joint.

How do blind rivets work?

Blind rivets are inserted into a pre-drilled hole in the materials to be joined. A rivet tool pulls the mandrel through the rivet body, causing the blind end to expand and form a tight joint. Once the mandrel reaches a predetermined tension, it snaps off, leaving a securely fastened assembly.

What are blind rivets used for?

Blind rivets are used in various applications, including aerospace, automotive, construction, and electronics, where it's challenging to access both sides of the materials being joined.

What tips do you have for how to install blind rivets?

To install a blind rivet, insert it into a pre-drilled hole in the materials to be joined. Use a rivet tool to pull the mandrel through the rivet body, causing it to expand and form a secure joint. The mandrel will snap off when the installation is complete.

Are blind rivets waterproof?

Closed-end blind rivets, also known as sealed blind rivets, are designed to create a watertight seal, preventing the passage of liquids or gases. They are ideal for applications requiring a sealed joint.
