Automotive Interior and Body Blind Rivet Nuts

Automotive Blind Rivet Nuts

High-Performance One-Sided Fastening Solutions for Vehicle Body Panels and Interior Assemblies

Overview

Automotive blind rivet nuts are engineered as a single-sided, weld-free fastening solution for modern vehicle manufacturing and repair. They are widely used in body panels, interior assemblies, and lightweight structures, especially in aluminum bodies and new energy vehicles (EVs).

With advanced designs such as the large-cap rivet nut, these fasteners provide enhanced load distribution, improved anti-rotation performance, and reliable thread strength—making them ideal for thin sheets and dissimilar-material connections.

Why Blind Rivet Nuts Are Essential in Automotive Applications

Automotive structures increasingly require:

• Lightweight materials (aluminum, galvanized steel)

• Hybrid material joining

• High assembly efficiency

• Reliable fastening without thermal distortion

Blind rivet nuts solve these challenges by enabling:

• One-sided installation in enclosed structures

• No welding or tapping required

• Consistent and repeatable thread formation

They are now a standard solution in automotive EV assembly and traditional vehicle production.

2. Drilling

• Hole diameter typically 0.1–0.3 mm larger than the rivet nut       outer diameter

3. Surface Preparation

• Remove burrs, oil, and contaminants

• Ensure clean contact surfaces

4. Adhesive Application (Optional)

• Apply structural adhesive in a controlled pattern

• Enhances sealing and vibration resistance

5. Rivet Nut Installation

• Use manual or pneumatic rivet nut tools

• Ensure proper deformation and seating

6. Quality Inspection

• Check for:

• Proper alignment

• No loosening

• No panel deformation or cracks
