Blind rivet GESIPA 6310443 Steel/Steel 4×8 mm flat head for 2.5–4.5 mm

The GESIPA blind rivet 4x8 mm is a high-quality fastening solution engineered for secure and permanent connections in various industrial and construction applications. Featuring a robust steel body and a steel mandrel, this rivet provides excellent structural integrity and resistance to vibration. The flat head design ensures a clean, low-profile finish, making it an ideal choice for projects where surface aesthetics and reliable performance are equally important.

Advantages

This steel-on-steel blind rivet offers superior strength compared to aluminum alternatives, ensuring that joints remain stable under mechanical stress. The precision manufacturing by GESIPA guarantees consistent installation results and reliable clamping force. Its design is specifically optimized for materials with a total thickness ranging from 2.5 to 4.5 mm, providing a versatile solution for sheet metal assembly and general repair work.

Suitable for

• Fastening sheet metal components in automotive repairs
• Assembly of metal frames and structures
• General construction and manufacturing tasks
• Joining mixed materials where high vibration resistance is required

When it may not be suitable

This rivet is not recommended for applications involving highly corrosive environments, as the steel construction may be susceptible to oxidation if not properly treated or coated. Additionally, it is not suitable for materials thinner than 2.5 mm or thicker than 4.5 mm, as the grip range is strictly defined for optimal joint integrity.

Key specifications

• Material: Steel body and steel mandrel
• Rivet diameter: 4 mm
• Rivet length: 8 mm
• Grip range: 2.5–4.5 mm
• Head type: Flat head

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 flat head sits flush against the surface. Using a compatible blind rivet tool, engage the mandrel and actuate the tool. The tool will pull the mandrel, deforming the rivet body to create a secure joint on the blind side, and then snap off the excess mandrel once the installation is complete.

What to consider before purchase

• Ensure the total thickness of the materials to be joined falls within the 2.5–4.5 mm range
• Verify that your rivet tool is compatible with 4 mm diameter steel rivets
• Consider the environmental conditions to determine if steel is the appropriate material for your specific application

Usage recommendations

Always use a properly calibrated riveting tool to ensure the mandrel breaks at the correct tension, preventing damage to the workpiece or an incomplete joint.
