GESIPA 1433455 Blind Rivet Stainless Steel 4x12 mm

The GESIPA 1433455 blind rivet is a high-quality cup-type fastener designed for applications requiring air- and water-tight connections. Manufactured from durable A2 stainless steel, this rivet features a dome head and provides excellent corrosion resistance for both industrial and home assembly projects. The closed-end design prevents fluids and moisture from passing through the rivet body, ensuring reliable performance in demanding environments.

Advantages

The primary benefit of the GESIPA CAP blind rivet is its cup-like structure, which creates a seal that is inherently resistant to air and moisture penetration. By preventing fluids from trickling through the fastener, it is an ideal solution for applications where sealing is critical. Constructed from high-grade stainless steel, the rivet offers superior longevity and resistance to environmental degradation, making it suitable for long-term use in various metalwork and assembly tasks.

Suitable for

• Creating air-tight and water-tight joints in metal sheets
• Applications requiring high corrosion resistance
• Professional metalwork and assembly projects
• Fastening tasks where moisture ingress must be prevented

When it may not be suitable

This rivet is not recommended for applications where significant hole filling is required, as the design limits the deformation of the rivet body during installation. It is also less effective in scenarios with high borehole tolerances, as the specific technical constraints of the cup design require precise preparation to ensure a secure connection.

Key specifications

• Material: A2 Stainless steel
• Rivet diameter: 4 mm
• Rivet length: 12 mm
• Head diameter: 8.5 mm
• Quantity: 500 pieces

How to use

To achieve a reliable and tight connection, careful preparation of the borehole is essential. The diameter of the hole should be kept as small as possible to ensure the rivet functions correctly over time. During the installation process, the rivet is inserted into the prepared hole and set using a compatible riveting tool. Because the mandrel is fixed within the hollow body for technical reasons, ensure the tool is properly aligned to facilitate a secure fastening without over-stressing the material.

What to consider before purchase

• Verify that the borehole diameter matches the requirements for a tight fit
• Ensure the application does not require high hole-filling capabilities
• Confirm the material compatibility with the surfaces being joined

Usage recommendations: For optimal performance and long-term sealing, always use the correct riveting tool and ensure the borehole is drilled to the minimum necessary diameter to maintain the integrity of the cup-type seal.
