Rivet Nut vs Press Rivet Nut: How to Choose the Right Sheet Metal Fastening Solution?

Engineering Guide for Selecting Blind Rivet Nuts and Compression Rivet Nuts

In sheet metal assembly, creating a reliable threaded connection can be challenging, especially when the material is too thin for tapping or when access is available from only one side.

Two common fastening solutions are blind rivet nuts and press rivet nuts (self-clinching nuts). Although both products provide internal threads for screw fastening, their installation methods, application conditions, and performance advantages are different.

JUXIN FASTENERS provides professional OEM rivet nut solutions, including blind rivet nuts, hex rivet nuts, countersunk rivet nuts, closed-end rivet nuts, and custom fastening components for automotive, industrial equipment, electronics, and sheet metal manufacturing applications.

Understanding the differences between rivet nuts and press rivet nuts helps engineers select the most reliable fastening method for their products.

What Is a Blind Rivet Nut?

A blind rivet nut, also known as a threaded insert nut, rivnut, or blind nut, is a mechanical fastener designed to create a strong internal thread in thin sheet materials.

Unlike traditional nuts that require access from both sides, a blind rivet nut can be installed from one side only.

During installation, a special rivet nut tool pulls the threaded mandrel, causing the body of the rivet nut to expand behind the material. This creates a strong mechanical lock between the fastener and the sheet metal.

Main Advantages of Blind Rivet Nuts

• One-side installation

• Suitable for thin sheet metal and hollow structures

• No welding required

• No heat damage to surrounding materials

• Creates strong reusable threads

• Suitable for maintenance and repeated assembly

• Available in various materials and finishes

Blind rivet nuts are widely used as an alternative to welded nuts and tapped holes.

What Is a Press Rivet Nut?

A press rivet nut, also called a self-clinching nut or clinch nut, is installed by pressing the nut into a pre-punched hole in sheet metal.

The special locking teeth or knurled features on the nut body penetrate into the sheet material. During pressing, the surrounding metal flows into the locking groove, creating a permanent mechanical connection.

Press rivet nuts require a suitable press machine or riveting equipment for installation.

Main Advantages of Press Rivet Nuts

• Fast installation in high-volume production

• Excellent resistance against rotation

• Clean surface appearance

• No additional welding process required

• Ideal for automated sheet metal production

Difference Between Blind Rivet Nut and Press Rivet Nut

When Should You Choose a Blind Rivet Nut?

A blind rivet nut is recommended when installation conditions make press riveting unsuitable.

Typical situations include:

1. Limited Access From One Side

If the backside of the material cannot be reached, a blind rivet nut is the ideal solution.

Examples:

• Closed profiles

• Tubular structures

• Equipment housings

• Vehicle components

• Finished assemblies

2. Irregular or Complex Component Shapes

Press rivet equipment requires the workpiece to be positioned correctly.

However, many industrial components have:

• Curved surfaces

• Irregular shapes

• Deep structures

• Limited installation space

In these cases, blind rivet nuts provide greater installation flexibility.

3. Materials That Cannot Be Welded

Traditional welding nuts may cause:

• Material deformation

• Heat damage

• Surface discoloration

• Additional finishing requirements

Blind rivet nuts eliminate these problems because they are installed mechanically without heat.

4. Thin or Sensitive Sheet Materials

For thin sheet metal, tapping threads directly may result in:

• Weak thread engagement

• Thread stripping

• Reduced fastening strength

A rivet nut for sheet metal provides a stronger and more reliable threaded connection.

How to Select the Right Rivet Nut?

Engineers should consider the following factors:

1. Material Thickness

Select the correct rivet nut according to the sheet thickness range.

2. Installation Environment

Consider whether access is available from both sides or only one side.

3. Required Strength

For high torque and vibration environments, hex rivet nuts may provide better performance.

4. Corrosion Requirements

Select suitable materials and surface treatments according to operating conditions.
