What are rivet nuts?
Rivet nuts, also known as rivnuts, nutserts, blind rivet nuts, or threaded inserts, are one-piece internal thread inserts that can be installed in sheet metal and composite materials from one side to create a permanent and reusable thread.
These versatile creations come in a range of materials, and with so many different types of rivet nuts on the market, there are a few things you should keep in mind when shopping for rivnuts.
At Rivetlab, weโve compiled a comprehensive rivet nut guide so you can find everything you will ever need to know about rivet nuts! Whether youโre tossing up different materials, sizes or the type of tools to use โ we have you covered at RivetLab!
Types of Rivet Nuts
Rivet nuts come in various types, each designed for specific applications and materials. Understanding the different types can help you select the right rivet nut for your project:
- Open-end rivet nuts: These are the most common type and are used for general-purpose applications. They allow the bolt to pass through completely and provide strong torque resistance.ย
- Closed-end rivet nuts: They provide a sealed end, preventing moisture and debris from entering the thread.
- Large flange rivet nuts: These are perfect for applications where a large bearing surface is required. The wide flange distributes the load over a larger area, reducing the risk of material deformation.
- Low-profile rivet nuts: When space is limited, low-profile rivet nuts are the go-to choice. Their compact design allows for installation in tight spaces without compromising strength.
- Hex nutserts: Used in applications where a high level of torque is needed. Their hexagonal shape prevents rotation, ensuring a secure fit.
By understanding the specific advantages of each type, you can make an informed decision and select the best rivet nuts for your needs.
Are rivet nuts versatile?
Yes, they are highly versatile. Rivet nuts are a reliable product for various fastening solutions. Rivet nuts come in different materials, such as steel, aluminium, stainless steel, brass and rubber. They can be installed into materials such as metal, plastic, carbon fibre, wood and more, where conventional hot welding is impractical. Rivet nuts are available in various sizes as well as body and flange shapes. They feature faster and easier assembly at reduced costs, so they are commonly used in industries and applications, including aerospace and agricultural equipment, medical technology, construction, automotive industry, electronic appliances, furniture assembly, HVAC, boat building, playground equipment and more.
Most rivet nuts need to be installed by using a rivnut tool. Depending on how the setting power is generated, rivnut tools can be categorised as manual rivet nut tools, battery or cordless rivnut guns and air nutsert guns.
Should I use a power rivet nut gun or a manual rivet nut gun?
When choosing a rivet nut gun, the first thing to consider is whether you need a power tool or a hand/manual tool. It depends on the volume of rivet nuts you plan to install. If it is a one-off project and you are looking at less than 100 rivet nuts in total, perhaps a hand tool is sufficient. If you plan to use the tool every day and go through hundreds of rivet nuts, then a power tool is worth the investment.
What's better, a cordless rivnut gun or an air rivet nut gun?
The choice between these two depends on the location you plan to work in. If you are working on a job site without ready access to a compressed air supply, a battery-operated tool would be ideal. An extra battery is recommended for volume installations. If you are working in a factory or in one location, an air rivet nut gun could offer a faster solution for high-volume users.
The good news is that though air rivet nut guns generally provide more power, quality cordless nutsert guns these days offer fast installation speed and large setting capacity as well. Some battery tools can reach up to M12 in stainless steel. The Gesipa Firebird Pro Gold S nutsert gun is a good example. This presents more options for users searching for a good balance tool between convenience and efficiency.
Rivet Nut Installation
Installing rivet nuts is a straightforward process that can be accomplished using a variety of tools, including manual, cordless, and air-powered tools. Here's a step-by-step guide to installing rivet nuts:
- Drill a hole: Start by drilling a hole in the material to be fastened. Ensure the hole size matches the rivet nut's specifications.
- Insert the rivet nut: Place the rivet nut into the drilled hole.
- Expand the rivet nut: Use a rivet nut tool to install the rivet nut, securing it in place. The tool pulls the mandrel, causing the rivet nut to deform and grip the material tightly.
Does thread size and material matter?
The next question is what thread size and type of material the rivet nuts you are working with. Most rivnut tools are compatible with a range of rivnut sizes. They come with a full set of nosepieces and mandrels, so you donโt have to buy multiple tools. Check the toolโs setting capacity and make sure the size of rivnut you install is in the working range.
The material of rivnut is another factor to consider. Stainless steel rivnuts require more pulling force to install. So if you are in this material zone, double check the material setting capacity description and make sure the tool is capable of stainless steel rivnuts of that size.

Safety Precautions
When working with rivet nuts, itโs crucial to follow safety precautions to avoid injury and damage. Here are some key safety tips:
- Wear protective gear: Always wear safety glasses and gloves to protect yourself from flying debris and sharp edges.
- Use the correct tool: Ensure you are using the appropriate tool for the job, whether it's a manual, cordless, or air-powered tool.
- Follow manufacturer's instructions: Adhere to the manufacturer's guidelines for installation and removal to ensure proper use and avoid accidents.
- Secure the material: Make sure the material being fastened is stable and secure before starting the installation process.
- Avoid over-tightening or under-tightening: Properly set the rivet nut to prevent damage to the material and the tool, ensuring optimal performance.
By following these safety precautions, you can work with rivet nuts confidently and safely.
