Advantages of Rivet Nuts

Access to blind locations
Rivnuts are blind threaded inserts, which means they can be installed securely from one side of a workpiece. Blind inserts are perfect for applications like tubular frames and other parts that are difficult to reach into.

Easy to install
Rivet nuts install in seconds with a hand tool (low volume) or a pneumatic power tool (high volume). Unskilled labor can be trained in minutes to achieve a repeatable high-quality installation.

Less likely to torque out
Rivet nuts don't depend on a weld to stay in place. Rivet nuts also come in hex body, which provides the ultimate anti-spin, anti-torque protection.

Less likely to distort your parent material
When installed with care, rivet nuts should not distort your parent material, including finishes such as plating or paint.

Able to be installed in a greater variety of materials
Rivet nuts can be installed in virtually any type of material, such as tubing, hard metals, soft metals, plastics, or ceramics.

Application of Rivet Nuts

Automotive Manufacturing
In modern automotive production, rivet nuts are widely used for internal threading in lightweight structures such as aluminum and thin steel sheets. Compared to traditional welding, rivet nuts enable faster installation without compromising the base material—making them ideal for blind holes and post-assembly installations.

Electrical Cabinets and Control Panels
In electrical cabinets, power distribution units, and industrial control systems, rivet nuts provide reliable threaded connections on sheet metal panels. They allow screws to be removed and reinstalled repeatedly, ensuring convenient maintenance.

Appliance Housings

Rivet nuts are particularly suitable for the metal housings and frame structures of appliances such as air conditioners, washing machines, and refrigerators. They enable high-speed, high-efficiency installation on production lines.

Rail Transit and Elevators

For high-vibration and high-strength structural applications—such as trains, subways, and elevators—rivet nuts provide durable and stable internal threads, able to withstand frequent operation and mechanical stress.

Industrial Equipment Assembly

In the manufacturing of industrial automation equipment, machinery structures, robotics, and electrical enclosures, rivet nuts offer fast and strong fastening across various base materials, including stainless steel, coated steel, and composite plastic panels.

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.

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.

Guidelines for installing rivet nuts

Preparation

Drill a Hole: A hole is drilled in the material where the rivet nut will be installed. The hole diameter must match the specifications for the rivet nut being used.

Inserting the Rivet Nut

Place the Rivet Nut: The rivet nut is inserted into the drilled hole, with the flange resting on the material's surface.

Using the Installation Tool

Thread the Mandrel: The installation tool has a threaded mandrel that matches the internal threads of the rivet nut. The mandrel is threaded into the rivet nut.

Pull the Mandrel: The tool pulls the mandrel towards the material surface, which causes the unthreaded portion of the rivet nut body to deform and expand.

Forming the Bulb: As the mandrel is pulled, the body of the rivet nut is compressed, causing it to bulge outwards and grip the backside of the material. This bulge creates a solid mechanical lock that firmly holds the rivet nut.

Completion

Release the Tool: Once the rivet nut is securely installed, the installation tool is removed by unthreading the mandrel.

Ready for Use: The rivet nut now provides a robust and threaded connection in the thin material, prepared to accept a bolt or screw.

FAQ

Q: I need a customized fastener, but it's not on your website. What do I do?

A: Please send us your request with detailed drawings or photos, then we will make the quotation for you accordingly.

Q: In general, how long can delivery be made after receiving an order?

A: Regular orders can be completed and shipped within 15-20 working days after receiving the deposit and confirming product details.

Q: During the product usage process, if we encounter technical problems, can you provide technical support?

A: Sure. We have a professional technical team that can provide you with technical consultation and guidance through methods such as telephone, email, or video conference.

Q: What is the packaging method of the product?

A: 50KG bag and pallet.

Q: What are rivnuts and how do they work?

A: Rivnuts, also known as rivet-nuts, are tubular hardware components used to fasten two pieces of sheet metal together. They are placed into pre-drilled holes and bucked into place, creating a permanent internal thread in the sheet metal. This allows you to attach and detach components easily using proper-sized bolts.

Q: Can rivnuts be used in applications with thin or weak sheet metal?

A: Yes, rivnuts are particularly useful for adding load-bearing threads to thin or weak sheet metal parts. By buckling a rivnut during installation, it creates a durable anchor that is stronger than tapping and less likely to be pulled out easily.

Q: Are rivnuts suitable for hard-to-reach areas in assemblies?

A: Absolutely! Rivnuts are blind threaded inserts, allowing for secure installation from one side of the workpiece. This feature makes them ideal for applications with blind locations or parts that are difficult to reach into, such as tubular frames or similar components.

Q: Are rivnuts installation-friendly and compatible with various materials?

A: Yes, rivnut installation is a simple and practical solution. It doesn't require heat, electricity, or tapping, making it a damage-free process. Additionally, rivnuts can be installed in a variety of materials, including steel, plastic, and fiberglass. They come in different shapes, sizes, and styles to suit your specific needs.

Q: Are rivet nuts permanent?

A: Blind rivet nuts are classified as permanent fasteners. There are temporary fasteners, and there are permanent fasteners. Temporary fasteners can be removed after installation, whereas permanent fasteners cannot be removed after installation. Blind rivet nuts fall under the latter category.

Q: Can you reuse rivet nuts?

A: Rivet nuts are non-reusable permanent fasteners. If removal is required because of poor installation or because the application will be disassembled, removal tools exist, but it may be helpful to have alternative removal methods.
