What are spread rivets?

Spread rivets, also known as umbrella or triform rivets, are specially designed fasteners that split into three equal parts behind the material during installation. This creates a large contact surface and a strong connection, especially with soft or thin materials.

Applications of the spread rivet

These spread rivets are ideal for various applications:

• Automotive sector: Attaching license plates, repairing window mechanisms, and mud flaps.
• Construction sector: Installing plasterboard, PVC frames, and other light structures.
• Caravan construction: Securing interior panels and other components.

Advantages of the spread rivet

• Even clamping force: The large contact surface distributes the clamping force evenly over the material, preventing damage.
• Suitable for soft materials: Ideal for materials such as wood, plastic, plasterboard, and insulation material.
• Easy installation: Can be installed with standard blind rivet tools.

Technical specifications

• Diameter: 4.0 mm
• Length: 18 mm
• Clamping range: 3.0 - 7.0 mm
• Sleeve material: Aluminium
• Mandrel material: Aluminium
• Head type: Dome head

Installation instructions

1. Preparation: Drill a hole with a diameter of 4.2 - 4.5 mm in the material to be fastened.
2. Placement: Insert the spread rivet through the hole.
3. Riveting: Use a suitable blind rivet tool to pull the rivet until the mandrel breaks off.

Important considerations

• Material compatibility: Ensure the material to be fastened falls within the clamping range of the rivet.
• Hole diameter: Use the recommended drill diameter for optimal performance.
• Tool: Use a suitable blind rivet tool for proper installation.

With these spread rivets, you achieve reliable and durable connections in various applications.
