How do Rivet Nuts Work ?
In order to solve the shortcomings of thin metal plate, thin tube welding nut easy to melt, tapping the internal thread easy to slip, BF Goodrich invented the rivet nut in 1930.
Because of their practicality, rivet nuts are now widely used in a variety of sheet metal connections, including automotive, machine building, and aerospace. So do you know how do rivet nuts work?
Below I will cover several aspects of how rivet nuts work and why they provide a strong connection.

What is a Rivet Nut?
A rivet nut is a special type of threaded fastener. It is a device that acts to form a threaded hole and provide a threaded connection in a thin plate, pipe or other thin material.
The rivet nut is similar in appearance to a nut, but the rivet nut is threaded on the inside. It has a flat bottom and an open top with grooves and indentations on the bottom that increase the resistance to rotation forces with the material.
Rivet nut can be made in different fabrication materials such as steel, aluminum, stainless steel, copper, carbon steel, etc. depending on your project needs. They come in a variety of different sizes and thread specifications, which you can customize from the rivet nut manufacturer according to your specific needs.
How do Rivet Nuts Work ?
The essence of the rivet nut is to make a tight connection by expansion. It is not possible to use bolts or screws when making fastening connections in thin plates. Therefore, a rivet nut is required to provide a connection point for bolts or screws.
The rivet nut is threaded by applying pressure to deform the rivet nut horizontally.The youtube video below shows you in detail how do rivet nuts work.
The rivet nut application consists of the following components: the rivet nut, the rivet nut tool, the substrate on which the rivet nut is to be installed, the bolt or screw. The rivet nut connects the parts by tightly joining the bolts together through the mechanics of the threads inside it. The rivet nut is pulled using a screw on a rivet gun, which compresses the rivet nut longitudinally and creates a raised deformation at the top, thus clamping the riveted joint.
What are the Benefits of Rivet Nuts?
Rivet nuts provide a fast, reliable and cost-effective solution for connecting sheet metal parts to each other. Rivet nuts have many advantages over nuts and bolts.
Seven Advantages of Rivet Nuts：
- Strong and reliable threaded connections provide a durable and dependable anchor point for bolts or other threaded fasteners.
- Ability to distribute the load over a large surface area. Prevents material deformation or damage compared to conventional nuts.
- Rivet nuts can be assembled significantly faster than methods such as welding or crimping. It can effectively reduce production time and cost.
- Rivet nuts create a flat, low-extension appearance on the surface of the material. Improves the overall aesthetics of the finished product.
How to Choose the Right Rivet Nut for Your Project?
Do you want to understand in more detail how do rivet nuts work? Box back to How do rivet nuts provide a secure connection for your project? Below I will explain in detail how each step of the rivet nut works in six areas.
Choose Right Rivet Nuts
How to choose the right rivet nut for your project?You need to consider many perspectives, such as the required application and material, the appropriate type of rivet nut and specifications.
Material Type: The first thing to consider before wholesaling rivet nuts is which type of rivet nut to use. Different materials of rivet nuts are used in different scenarios. Such as aluminum, stainless steel, carbon steel, copper, plastic, composite materials and so on. You need to make sure that the rivet nut and the material to be riveted are compatible so that there is a stable threaded connection.
Suitable Outer Diameter and Length: Before wholesaling rivet nuts, you need to have a clear idea of the diameter and length of the rivet nuts you need. Make sure that the specification of the rivet nut matches the size of the hole. The rivet nut should not be much larger or smaller than the diameter of the hole if it is to function correctly, ensuring that the threaded portion should be fully embedded in the material.
Rivet nut manufacturers also confirm product information based on this.
Rivet Nut Types: There are many types of rivet nuts to solve a variety of different application scenarios. From the material point of view, including stainless steel rivet nuts, carbon steel rivet nuts, aluminum rivet nuts, copper rivet nuts and so on. In terms of appearance, there are hex rivet nut, round rivet nut, open end rivet nut, closed end rivet nut, countersunk rivet nut and so on.
Provide Suitable Holes for Rivet Nuts
In order to ensure the tightness of the rivet nut connection, in general, the holes in the plate should be 1mm more than the outer diameter of the rivet nut. that is to say, when the outer diameter of the rivet nut is 4.7mm, the open hole should be 4.8mm. according to a large number of practice has shown that the tightness of this is the best.
The following table shows the relationship between the outside diameter of the rivet nut and the corresponding hole.
| Rivet Nut Outer Diameter | Diameter of Hole |
|---|---|
| 4.9 | 5 |
| 5.9 | 6 |
| 6.9 | 7 |
| 8.9 | 9 |
| 10.9 | 11 |
| 12.9 | 13 |
| 11.9 | 12 |
| 14.9 | 15 |
| 15.9 | 16 |
Correct Insertion of The Rivet Nut
Insert the rivet nut into the drilled hole, you need to make sure that the head of the rivet nut is flush with the surface of the material. The riveting is then accomplished by means of a riveting tool so that the threaded portion of the rivet nut is fully seated in the hole.
Installation of Rivet Nuts
There are many tools for installing rivet nuts, but they are broadly categorized into three types: hand rivet nut tools, electric rivet nut tools and pneumatic rivet nut tools.
Installation of rivet nuts can be accomplished regardless of the installation tool used. Installing rivet nuts is a simple process that can be accomplished in a few easy steps.
- Screw the rivet nut onto the mandrel of the tool.
- Place the rivet nut into the pre-drilled hole. Start the tool and pull the rivet nut.
- The rivet nut is deformed and tightly attached to the material.
- Reverse the tool out of the center of the rivet nut
Where to Buy Rivet Nuts
There are many ways to buy rivet nuts. These include buying in small quantities, buying in bulk and customizing rivet nuts.
