Blind rivet GESIPA 4x8 mm countersunk head KS for 3.0–5.0 mm materials, pack of 500

The GESIPA 4x8 mm blind rivet with a countersunk head is a professional-grade fastening solution designed for creating secure, permanent connections in applications where access is limited to a single side. These rivets are engineered to provide a flush surface finish, making them ideal for projects where aesthetics and smooth profiles are required. With a grip range of 3.0 to 5.0 mm, they offer versatility for various sheet metal and panel assembly tasks.

Advantages

These blind rivets offer exceptional reliability and vibration resistance, ensuring that joints remain intact even under demanding conditions. The countersunk head design allows the rivet to sit flush with the material surface, which prevents snagging and provides a clean, professional appearance. Manufactured to high standards, these fasteners provide consistent performance and ease of installation, significantly reducing assembly time in both industrial and workshop environments.

Suitable for

• Joining thin sheet metal components
• Attaching panels where a flush surface is required
• Light structural assemblies
• Applications with one-sided access

When it may not be suitable

This rivet is not intended for heavy-duty structural load-bearing applications where high shear or tensile strength is required. It is also not suitable for materials thicker than 5.0 mm or thinner than 3.0 mm, as the grip range is specifically calibrated for these dimensions.

Key specifications

• Diameter: 4 mm
• Length: 8 mm
• Head type: Countersunk (KS)
• Grip range: 3.0–5.0 mm
• Quantity: 500 pieces

How to use

To install the rivet, first drill a hole of the appropriate diameter into the materials being joined. Insert the rivet into the hole until the countersunk head is flush with the surface. Using a compatible blind rivet tool, pull the mandrel through the rivet body. The tool will compress the rivet, creating a secure connection on the blind side, and automatically snap off the excess mandrel once the installation is complete.

What to consider before purchase

• Ensure the total thickness of the materials being joined falls within the 3.0–5.0 mm range.
• Verify that the drill hole diameter matches the rivet size requirements.
• Confirm that the material type is compatible with the rivet material to prevent galvanic corrosion.

Usage recommendations

Always use a properly calibrated riveting tool to ensure consistent pressure and a secure fit. Wear appropriate eye protection during the installation process to prevent injury from the snapping mandrel.
