Flat Head Hex Rivet Nut Solutions for High-Strength Sheet Metal Fastening

Reliable Hexagonal Blind Rivet Nuts for Industrial Equipment, Automotive and Structural Applications

In modern manufacturing, creating strong threaded connections in thin sheet materials can be challenging. Traditional welding nuts and tapped holes are often limited by material thickness, installation access, and production efficiency.

A Flat Head Hex Rivet Nut, also known as a Flat Head Hexagonal Rivet Nut, Hex Body Blind Rivet Nut, or Threaded Insert Nut, provides a reliable solution for adding strong internal threads to sheet metal, tubes, and hollow structures.

With its hexagonal body design and flat flange head, the flat head hex rivet nut offers excellent anti-rotation performance, high torque resistance, and easy installation.

JUXIN FASTENERS specializes in manufacturing custom rivet nuts and OEM fastening solutions for global customers in automotive, industrial equipment, electrical enclosures, machinery, and sheet metal fabrication industries.

What Is a Flat Head Hex Rivet Nut?

A Flat Head Hex Rivet Nut is a blind threaded insert designed to create a permanent threaded connection in materials where access is available from only one side.

Unlike standard round rivet nuts, the hexagonal body provides additional mechanical locking performance. The six-sided body prevents rotation inside the installation hole when the bolt is tightened or removed.

The flat head flange distributes installation loads over a larger surface area, improving stability and reducing stress on thin sheet materials.

A typical flat head hex rivet nut consists of:

• Flat head flange

• Hexagonal anti-rotation body

• Internal threaded section

• Deformation area for installation

Key Advantages of Flat Head Hex Rivet Nuts

1. Superior Anti-Rotation Performance

The hexagonal body design is one of the biggest advantages of this type of rivet nut.

Compared with round body rivet nuts, hex rivet nuts provide stronger resistance against spinning, making them suitable for applications requiring high tightening torque.

Benefits include:

• Improved fastening reliability

• Higher torque resistance

• Stable connection under vibration

• Reduced risk of fastener rotation

2. Strong Threaded Connections in Thin Materials

Many sheet metal components cannot be tapped directly because the material thickness is insufficient.

A flat head hex rivet nut for sheet metal solves this problem by providing a durable internal thread without:

• Welding additional nuts

• Increasing material thickness

• Complex machining processes

It is widely used as an alternative to:

• Weld nuts

• Press nuts

• Traditional tapped holes

3. Easy Installation and Maintenance

Flat head hex rivet nuts can be installed using manual, pneumatic, or hydraulic rivet nut tools.

The installation process is fast and efficient:

1. Drill the correct installation hole.

2. Insert the rivet nut.

3. Use the installation tool to expand the rivet nut body.

4. The rear section deforms and locks securely.

5. Install the required bolt or screw.

Because the internal thread remains reusable, maintenance and replacement are simple.

4. Large Bearing Surface Design

The flat head provides a wider contact area between the rivet nut and the base material.

This helps:

• Improve load distribution

• Reduce material deformation

• Increase assembly stability

It is especially suitable for thin sheet metal structures.
