What Are Rivet Nuts?

Rivet nuts, also known as threaded inserts or blind nuts, are one-piece internally threaded fasteners that can be installed from one side of a workpiece. They provide strong, reusable threads in materials that are too thin or brittle to be tapped directly. They are widely used in automotive, aerospace, electronics, and construction industries.

Materials of Rivet Nuts

1. Steel (Carbon steel, Stainless steel) – High strength, corrosion-resistant (especially stainless steel).

2. Aluminum – Lightweight, good corrosion resistance.

3. Brass – Excellent corrosion resistance, used in electrical applications.

4. Copper – Conductive, used in specific electrical applications.

Surface Treatments

1. Zinc Plating – Improves corrosion resistance (common for steel rivet nuts).

2. Anodizing (for aluminum) – Enhances durability and corrosion resistance.

3. Passivation (for stainless steel) – Removes free iron and improves corrosion resistance.

4. Nickel Plating – Provides additional wear and corrosion resistance.

Specifications

• Thread Size: M3, M4, M5, M6, M8, M10, etc. (Metric) or #4-40, #6-32, #8-32, etc. (Imperial).

• Body Diameter: Varies based on application (e.g., 4mm to 12mm).

• Grip Range: Typically 0.5mm to 6mm (material thickness it can secure).

• Installation Method: Manual or pneumatic rivet nut tool.

Applications

• Automotive: Panel fastening, interior trim, chassis components.

• Aerospace: Lightweight structural assemblies.

• Electronics: Securing PCBs, enclosures.

• Construction: Metal framing, HVAC systems.

• Furniture: Assembly of modular components.

Excellent Case: Automotive Panel Assembly

Scenario: A car manufacturer needs to attach a lightweight aluminum dashboard panel to a thin steel frame without welding or through-hole bolts.

Solution:

1. Material Choice: Aluminum rivet nuts (lightweight, corrosion-resistant).

2. Installation: Using a pneumatic rivet nut tool, workers install M5 rivet nuts into pre-drilled holes in the steel frame.

3. Result: The dashboard panel is securely fastened with screws, providing a strong, vibration-resistant joint without damaging the thin metal.

Benefits:
✔ No backside access needed (blind installation).
✔ Reusable threads for maintenance.
✔ Lightweight yet durable connection.
