What are Stainless Steel Blind Rivet Nuts?

Stainless steel blind rivet nuts, also known as rivet nuts, threaded inserts, or nutserts, are essentially internally threaded fasteners designed to be installed into thin materials where a regular nut and bolt wouldn't work. Imagine you're working with a sheet of metal that's too thin to tap threads into. That's where these little guys come in handy. They provide a strong, reliable thread in materials like sheet metal, plastic, and even composites.

The magic of stainless steel blind rivet nuts lies in their installation process. You insert the rivet nut into a pre-drilled hole and then use a special tool to deform the body of the nut on the blind side of the material. This creates a bulge or flange that securely grips the material, providing a robust threaded anchor point. Because they're made of stainless steel, they offer excellent corrosion resistance, making them ideal for outdoor applications or environments where moisture is a concern.

These fasteners are incredibly versatile and are used across a wide range of industries.

• Open-End Rivet Nuts: These have an open end that allows for the insertion of longer bolts or screws. They're a versatile option for a variety of applications.

Each type has its own unique advantages and is suited for different applications. When choosing a stainless steel blind rivet nut, it's essential to consider the specific requirements of your project, such as the material thickness, load requirements, and environmental conditions.

How to Install Stainless Steel Blind Rivet Nuts

Alright, let's get down to the nitty-gritty: how do you actually install these things? Don't worry, it's not rocket science! Here’s a step-by-step guide:

1. Gather Your Tools: You'll need a rivet nut installation tool (also known as a nutsert tool), a drill, drill bits (sized appropriately for the rivet nuts you're using), and safety glasses.
2. Drill the Hole: Drill a hole in the material where you want to install the rivet nut. Make sure the hole is the correct size for the rivet nut you're using. Too small, and you won't be able to insert the rivet nut. Too big, and the rivet nut won't grip properly.
3. Insert the Rivet Nut: Thread the rivet nut onto the mandrel of the installation tool. Then, insert the rivet nut into the pre-drilled hole.
4. Activate the Tool: Activate the installation tool. This will cause the tool to pull the mandrel back, deforming the body of the rivet nut on the blind side of the material. This creates a bulge or flange that securely grips the material.
5. Remove the Tool: Once the rivet nut is securely installed, remove the installation tool. The mandrel will unthread from the rivet nut, leaving you with a strong, threaded anchor point.
6. Inspect the Installation: Double-check that the rivet nut is properly installed and securely fastened. You should be able to see the deformed portion of the rivet nut gripping the material on the blind side.

Pro Tip: Always follow the manufacturer's instructions for your specific rivet nut installation tool. Different tools may have slightly different procedures.

Tips for Choosing the Right Stainless Steel Blind Rivet Nuts

Choosing the right stainless steel blind rivet nuts can be tricky. Here are some tips to help you make the right choice:
