The Complete Guide to Blind Rivet Nuts: Types, Installation, and Industrial Applications

What Are Blind Rivet Nuts?

Blind rivet nuts, also known as threaded inserts or rivet nuts, are specialized mechanical fasteners designed to create strong internal threads in thin sheets, tubes, and hollow structures where conventional nuts cannot be used.

A blind rivet nut consists of a tubular body with internal threads and a deformable rivet section. When installed using a rivet nut tool, the body collapses behind the base material, forming a secure mechanical lock.

This process creates a durable threaded insert that allows bolts or screws to be installed later.

Blind rivet nuts are widely used in industries such as:

• Automotive manufacturing

• Aerospace engineering

• Electrical equipment

• HVAC systems

• Machinery production

• Furniture manufacturing

Because they can be installed from one side of the workpiece, blind rivet nuts are particularly valuable for closed profiles, sheet metal enclosures, and tubular structures.

Key Advantages of Blind Rivet Nuts

One-Side Installation

Blind rivet nuts are designed for blind installation, meaning they can be installed from one side of the material without access to the backside.

This makes them ideal for:

• Hollow structures

• Enclosed housings

• Thin sheet assemblies

• Tubular frames

Strong and Reliable Threaded Connection

Blind rivet nuts create high-strength internal threads, enabling secure fastening using standard bolts or screws.

Once installed, the rivet nut provides excellent resistance to:

• Pull-out forces

• Torque loads

• Mechanical vibration

Ideal for Thin Materials

Traditional threaded connections often fail in thin sheet metal.

Blind rivet nuts can be installed in materials as thin as:

0.5 mm to 6 mm

This allows engineers to create reliable threaded connections in lightweight structures.

No Welding Required

Unlike welded nuts, blind rivet nuts do not require high-temperature welding.

Benefits include:

• No heat distortion

• No damage to coatings

• No oxidation risk

• Cleaner installation process

Fast Installation and High Efficiency

Blind rivet nuts can be installed quickly using:

• Manual rivet nut tools

• Pneumatic rivet guns

• Automated installation machines

This makes them suitable for high-volume manufacturing environments.

Common Types of Blind Rivet Nuts

Different applications require different types of rivet nuts.

Standard Blind Rivet Nuts

These are the most commonly used rivet nuts and are suitable for general industrial applications.

Features:

• Cylindrical body

• Internal threads

• Simple installation

Applications include sheet metal assemblies and equipment housings.

Jack Nuts

Jack nuts are designed specifically for soft or fragile materials.

During installation, the rivet body expands into four legs, distributing load over a larger surface area.

They are ideal for materials such as:

• Plastic

• Wood

• Fiberglass

• Thin composite panels

Closed-End Rivet Nuts

Closed-end rivet nuts feature a sealed end, preventing liquids or gases from passing through the fastener.

They are widely used in:

• Automotive structures

• HVAC equipment

• Electronic enclosures

Hex Rivet Nuts

Hex rivet nuts have a hexagonal body that prevents rotation inside the mounting hole.

They are ideal for applications requiring high torque resistance.

Blind Rivet Studs

Blind rivet studs create external threaded studs instead of internal threads.

They are commonly used for mounting:

• Electrical components

• Equipment brackets

• HVAC panels

Installation Process of Blind Rivet Nuts

Installing blind rivet nuts is simple and efficient.

Step 1 – Drill the Mounting Hole

Prepare a hole with the correct diameter for the rivet nut.

Step 2 – Insert the Rivet Nut

Place the rivet nut into the hole.

Step 3 – Engage the Installation Tool

Thread the rivet nut tool onto the internal threads of the rivet nut.

Step 4 – Apply Pulling Force

The tool pulls the fastener while compressing the rivet body, causing it to expand behind the material.

Step 5 – Remove the Tool

Once the rivet nut is fully set, the tool is removed, leaving a secure threaded insert.

Industrial Applications of Blind Rivet Nuts

Automotive Industry

Blind rivet nuts are widely used in automotive manufacturing for mounting components on thin sheet metal structures.

Applications include:

• Switchgear enclosures

• Control panels

• Cable management systems

HVAC Systems

HVAC equipment often requires fastening solutions for thin sheet metal panels.

Blind rivet nuts are used for:

• Ventilation systems

• Air-conditioning units

• Refrigeration equipment

Industrial Machinery

In machinery manufacturing, blind rivet nuts create reliable threaded mounting points for mechanical components.

Applications include:

• Equipment housings

• Protective covers

• Structural brackets

Why Engineers Choose Blind Rivet Nuts

Engineers choose blind rivet nuts because they provide:

• Reliable threaded connections

• Fast installation

• Compatibility with thin materials

• Cost-effective manufacturing solutions

As modern industries continue to adopt lightweight structures and sheet-metal assemblies, blind rivet nuts remain among the most versatile fastening technologies available.
