A Rivnut, also known as a threaded insert or a blind rivet nut, is a type of fastener used to create a threaded hole in materials that are too thin or too brittle to support a conventional tapped hole. It provides a reliable and durable way to join or secure components together.

How Does A Rivnut Work?
Here’s how a Rivnut works:
- Insertion: The Rivnut is designed to be inserted into a pre-drilled hole in the material. The hole should have a diameter slightly larger than the outer diameter of the Rivnut.
- Tool Selection: A specialized tool called a Rivnut setter or Rivnut tool is used to install the Rivnut. The tool typically consists of a handle and a head assembly.
- Thread Engagement: The Rivnut is placed into the hole, and the head of the Rivnut tool is aligned with the Rivnut. The tool is then operated, engaging the head of the Rivnut with the tool’s head assembly.
- Compression: As the tool is operated, it applies axial force to the Rivnut, causing it to collapse inwards. This collapsing action creates a strong grip on the material.
- Expansion: As the Rivnut collapses, it expands outward to fill the hole and forms a secure connection. The collapsed portion of the Rivnut forms internal threads that can accept a bolt or a screw.
- Removal of Tool: Once the Rivnut is securely installed, the tool is released, and the Rivnut setter is removed from the Rivnut.
- Threaded Hole: The installed Rivnut now provides a threaded hole in the material, allowing the attachment of bolts, screws, or other threaded fasteners.
Rivnuts are commonly used in applications where there is limited access to the backside of the material or where the material is too thin to tap a conventional thread. They are often used in automotive, aerospace, electronics, and sheet metal fabrication industries.

Choosing The Right Rivnut
Rivnuts, also known as threaded inserts, are a versatile fastening solution used in a variety of applications. When choosing the right rivnut, factors such as grip length and size must be considered. Calculating the required grip length ensures the rivnut will perform as intended.
Pairing the rivnuts with specific materials is crucial to achieve optimal results. For example, steel rivnuts work well with steel and aluminum materials. However, aluminum and brass rivnuts are better suited for softer materials like plastics and wood. Best practices for choosing rivnuts include carefully evaluating the factors mentioned above and testing prototypes before installation.
By choosing the right rivnut, your application will be secure and reliable.
Frequently Asked Questions For How Does A Rivnut Work
What Materials Can You Use A Rivnut On?
Rivnuts can be used on a variety of materials, including steel, aluminum, plastic, and fiberglass.
What Are The Advantages Of Using A Rivnut?
Rivnuts provide a strong, reliable hold and can be installed quickly and easily. They also don’t require access to the back of the material, making them a popular choice for blind installations.
Conclusion
After going through the whole concept of what is a rivnut and how it provides high strength and reliability, it is clear that it is a game-changer in the field of fastening technology. A rivnut utilizes advanced technology, making them an excellent alternative to traditional bolt fasteners.
