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. ## Breadcrumbs - [Fasteners](https://www.auto-service.be/en/fasteners) - [Blind rivets](https://www.auto-service.be/en/fasteners/blind-rivets) -
