What is a Rivet Nut Tool and Why is it Useful for Threaded Inserts?
A rivet nut is a one-piece, internally threaded insert. When you use a rivet nut tool, it compresses and deforms the nut on the “blind” side of the material, creating a permanent, bulged flange that locks it firmly in place. This provides a clean, strong thread, ready for a bolt. Rivet nuts are a type of blind rivet fastener used to create strong threaded connections in thin sheet metal and other materials.
The primary advantage is the ability to install threads in materials that are too thin to be tapped for a traditional screw or bolt. Think of it as adding a permanent nut to a piece of sheet metal under pressure, where you can’t easily reach the back side to tighten the fastener.
The key benefits include those that contribute to your success :
- Versatility: They work on a wide range of materials, including steel, aluminum, plastic, and composites.
- Strength: Rivet nuts provide a high-strength, load-bearing thread that resists pull-out.
- Effectiveness: Rivet nut tools are highly effective at providing secure, reliable threads in a variety of materials.
- Convenience: Installation is quick and can be done from one side of the workpiece, making it ideal for closed-off sections, such as tubing or box frames.
- Clean Finish: It provides a professional and flush finish without the need for welding or other complex fastening methods.
A fine rivet nut tool, manufactured to high standards, provides the necessary support and ensures consistent results. Using a good tool, along with a wrench, makes installation easier and works great for both professionals and happy DIYers.
Types of Rivet Nut Tools: Hand vs. Pneumatic
Rivet nut tools generally fall into two categories: manual (hand-operated) and pneumatic (air-powered). Many of these tools feature interchangeable heads, allowing users to easily switch between different sizes for various applications.
When installing rivet nuts, it is important to ensure that the holes in the sheet metal or panel are properly sized and placed to achieve a secure fit and prevent damage. High-quality rivet nut tools can often be repaired, which extends their lifespan and makes them a cost-effective investment.
These tools can be purchased from reputable suppliers, ensuring that products ordered ship on time, and some users may choose to sell their tools after completing a project.
As an alternative to rivet nut tools, a stud and washers can be used for mounting or securing components, providing a simple and effective DIY solution in certain situations. Rivet nuts were originally sold under the RIVNUT® trademark and are now widely available from various brands.
Hand Rivet Nut Tools
Manual tools are the most common choice for DIYers, home workshops, and mechanics who need portability. They operate using a lever or a squeeze mechanism that provides the mechanical advantage needed to set the rivet nut. When installing a rivet nut manually, a wrench can be used to hold the bolt head in place to prevent it from spinning while tightening the fastener.
- Plier-Style Tools: These are smaller and best suited for smaller rivet nuts (typically up to M6 or 1/4-20). They are lightweight and easy to use for light-duty applications, but require more hand strength for larger nuts.
- Lever-Style Tools: These tools, often featuring long handles (14-16 inches or more), provide significantly more leverage. This makes them ideal for setting larger and more robust rivet nuts (M8, M10, M12, and larger SAE sizes) with less physical effort. Most of the popular consumer kits fall into this category.
Pros:
- Affordable and widely available.
- Portable and doesn’t require an air compressor.
- Excellent for occasional use and on-the-go repairs.
Cons:
- Requires physical effort, which can be fatiguing for repetitive tasks, and significant time is spent when manually installing multiple rivet nuts.
- Slower than pneumatic tools for high-volume work.
Pneumatic (Air) Rivet Nut Tools
Pneumatic tools use compressed air to do the hard work of setting the rivet nut. With the press of a trigger, the tool pulls the mandrel and sets the nut in seconds. These are the go-to support tools for professional manufacturing, assembly lines, and high-volume repair shops. Pneumatic tools are known for their effectiveness in ensuring secure and precise installations. A good example is the UPWOOD Heavy Duty Air Hydraulic Rivet Nut Tool.
Pros:
- Extremely fast and efficient for repetitive tasks.
- Pneumatic tools deliver fast and consistent results, making them ideal for high-volume work.
- Requires minimal physical effort from the operator.
- Provides a consistent and reliable setting force.
Cons:
- Significantly more expensive than manual tools.
- Requires an air compressor, limiting portability.
- It can be overkill for the average DIY enthusiast.
In summary, a fine pneumatic tool can make a significant difference in professional settings, offering both speed and effectiveness for demanding applications.
Key Features to Look For in a Rivet Nut Tool
When shopping for a rivet nut tool, several features will determine its performance, durability, and ease of use.
- Material and Build Quality: Look for tools made from high-strength materials, such as heat-treated carbon steel or chromium steel. A robust build ensures the tool can withstand the high forces required to set rivet nuts without flexing or breaking. A fine tool, manufactured by reputable companies, ensures durability and reliability. A quality oil-resistant handle coating, such as TPR soft rubber, can also enhance grip and comfort.
- Effort-Saving Design: For manual tools, longer handles (16 inches is a good length) provide better leverage and reduce the effort needed. Some models, like the NOVORIK tool, feature an internal lever system specifically designed to multiply your force, making the job easier on your muscles.
- Mandrel Sizes and Compatibility: A good kit will come with a wide range of interchangeable mandrels to fit various rivet nut sizes, including both metric (M3, M4, M5, etc.) and SAE (10-24, 1/4-20, etc.) standards. The more mandrels included, the more versatile the tool. Some tools also feature interchangeable heads, allowing you to quickly adapt the tool for different applications and nut sizes, increasing versatility and convenience.
- Tool-Free Mandrel Changes: The ability to swap mandrels without needing extra wrenches is a considerable convenience. This feature, found on tools like the NOVORIK model, saves time and frustration, especially when you’re switching between different nut sizes on a single project.
- Value for Money: Investing in a good tool can save you money in the long run by reducing the need for replacements and ensuring reliable performance.
Safety Precautions When Using Rivet Nut Tools
When working with rivet nut tools, safety should always be a top priority to ensure both a successful installation and your personal well-being. Always wear safety glasses to protect your eyes from flying debris, and gloves to shield your hands from sharp edges on rivet nuts or sheet metal. Before starting any installation, inspect your tool for signs of wear or damage. Loose parts or worn mandrels can cause the nut to spin or the tool to slip, increasing the risk of injury.
Make sure your work area is clear and well-lit, and keep bystanders at a safe distance. Avoid applying excessive force during installation, as this can cause the rivet nut to spin in the hole or damage the threads. Always follow the manufacturer’s instructions for your specific tool and regularly maintain it by cleaning and lubricating moving parts. By taking these precautions, you’ll minimize the risk of accidents and ensure your rivet nut tool delivers reliable, safe results every time.

How to Use a Rivet Nut Tool: A Step-by-Step Guide
Using a rivet nut tool is straightforward once you get the hang of it. Here’s a general process for a manual lever-style tool, which you can see demonstrated in this video :
- Drill the Hole: Start by drilling a clean, correctly sized hole in your workpiece. The rivet nut should fit snugly but not require force to insert. Check the rivet nut manufacturer’s specifications for the exact drill bit size. Make sure the holes are the correct diameter to ensure a secure fit and prevent damage to the panel.
- Select the Right Mandrel: Choose the mandrel and nosepiece that match the size and thread of your rivet nut. Attach it securely to the tool.
- Thread the Rivet Nut: Screw the rivet nut onto the mandrel until it is flush with the end of the nosepiece.
- Insert into the Workpiece: Insert the rivet nut into the pre-drilled hole. Ensure the flange of the nut is sitting flush against the surface of the material.
- Set the Rivet Nut: Squeeze the handles of the tool together firmly. You will feel the tool pulling the mandrel, which compresses the body of the rivet nut on the other side. Continue squeezing until the handles come to a firm stop. This indicates the nut is fully set. If you are using a bolt and nut method, use a wrench to hold the bolt head steady to prevent it from spinning during installation.
- Release the Tool: Once the nut is set, unscrew the mandrel from the newly installed insert. On some tools, you turn a knob to release it; on others with an “auto-release” feature, simply pulling the handles apart may initiate the release.
- Inspect Your Work: You should now have a secure fastener and a threaded insert ready for your bolt.
