Blind Rivet Nuts Solutions for Sheet Metal Assembly Applications

Reliable Threaded Fastening Solutions for Thin Metal Panels, Enclosures and Industrial Manufacturing

In modern sheet metal manufacturing, creating strong and reliable threaded connections in thin materials has always been a challenge.

Traditional methods such as welding nuts or tapping internal threads often create several problems:

• Welding can cause deformation and surface damage

• Heat treatment may affect material performance

• Tapped threads in thin sheets may easily strip

• Assembly efficiency is reduced in high-volume production

Blind rivet nuts, also known as rivnut, threaded inserts, or blind threaded inserts, were developed to solve these challenges.

By installing a threaded insert through a single-sided riveting process, blind rivet nuts provide strong internal threads in thin metal sheets without welding or backside access.

Juxin Fasteners specializes in manufacturing blind rivet nuts, rivnuts, threaded inserts, and custom fastening solutions for global OEM customers.

Our blind rivet nut solutions are widely used in:

• Sheet metal fabrication

• Electrical cabinets

• Control panels

• Automotive components

• New energy battery packs

• Medical equipment

• Industrial machinery

• Aerospace structures

What Are Blind Rivet Nuts?

A blind rivet nut is a tubular threaded fastener designed to create a permanent threaded hole in thin materials where access is available from only one side.

Unlike conventional nuts, blind rivet nuts do not require:

• Welding equipment

• Rear-side access

• Pre-threading operations

During installation, the rivet nut is inserted into a pre-drilled hole and expanded using a special riveting tool. The deformation creates a strong mechanical lock between the insert and the sheet material.

This provides:

• Strong threaded connections

• High pull-out resistance

• Excellent torque resistance

• Fast installation

• Clean appearance

Why Choose Blind Rivet Nuts for Sheet Metal Applications?

1. Ideal Solution for Thin Metal Panels

Thin sheet metal often cannot provide enough thickness for reliable internal threads.

Traditional tapping methods may cause:

• Thread stripping

• Reduced fastening strength

• Limited screw engagement depth

Blind rivet nuts create strong load-bearing threads without increasing material thickness.

They are ideal for:

• Aluminum panels

• Steel sheets

• Stainless steel enclosures

• Thin-wall tubing

2. Replace Welding Nuts and Improve Production Efficiency

Welding nuts have traditionally been used for sheet metal assembly. However, welding processes may introduce problems:

• Heat distortion

• Surface discoloration

• Welding defects

• Additional labor requirements

Blind rivet nuts eliminate these issues.

Advantages:

✔ No welding required
✔ No heat deformation
✔ Faster assembly process
✔ Improved product appearance
✔ Reduced production cost

This makes blind rivet nuts an excellent alternative to welded nuts in modern manufacturing.

3. One-Side Installation Design

One of the biggest advantages of blind threaded inserts is that they can be installed from one side of the workpiece.

This is especially valuable for:

• Closed structures

• Hollow profiles

• Metal cabinets

• Tubular components

Applications where traditional nuts cannot be accessed can easily use blind rivet nuts.

4. Strong and Reliable Mechanical Performance

Although compact in size, blind rivet nuts provide excellent fastening performance.

Key advantages:

• High tensile strength

• Strong torque resistance

• Stable screw connection

• Reliable vibration resistance

They can replace many traditional fastening methods while improving assembly reliability.

Blind Rivet Nut Installation Process

Proper installation ensures maximum fastening performance.

Step 1: Select the Correct Rivet Nut

Selection should consider:

• Thread size

• Material thickness

• Base material

• Required strength

Common thread options:

• Metric threads

• Inch threads

• Custom thread sizes

Step 2: Prepare the Installation Hole

Create the correct hole size according to the rivet nut specification.

Suitable processes:

• Drilling

• Punching

• CNC machining

The hole diameter must be controlled accurately to ensure proper expansion.

Step 3: Insert the Blind Rivet Nut

Insert the rivet nut into the prepared hole.

Ensure:

• Correct alignment

• Proper seating

• No contamination around the hole

Step 4: Perform Riveting Installation

Use professional installation tools:

• Manual rivet nut tools

• Pneumatic rivet nut guns

• Hydraulic riveting equipment

During installation, the threaded section expands behind the panel, creating a permanent mechanical connection.

Step 5: Inspect Installation Quality

Check:

• Insert positioning

• Thread condition

• Rotation resistance

• Pull-out performance

A properly installed blind rivet nut should remain firmly fixed.
