Blind Rivet GESIPA 4x8 mm Large Flange, Grip 3.0–5.0 mm, Pack of 500

Blind Rivet GESIPA 4x8 mm Large Flange, Grip 3.0–5.0 mm, Pack of 500 are blind rivets designed for permanent, vibration-resistant fastening where access is available from one side. Each rivet features a large flange to distribute load over thin or soft materials and a 3.0–5.0 mm grip range to accommodate typical stack thicknesses in sheet metal and light fabrication. Supplied in a pack of 500, these blind rivets are intended for batch assembly, repair and production tasks that require consistent, repeatable joints using a blind-riveting tool.

Advantages

Large flange design reduces the risk of pull-through and increases bearing area on thin sheets and composite panels. The specified grip range allows secure clinching across varying material combined thicknesses without the need for shims. Being blind rivets, they enable installation from one accessible side, simplifying assembly in confined or obstructed spaces. Supplied in bulk quantity, the pack supports efficient workflow and reduces downtime by minimizing reloading frequency.

How to use

Select a matching blind-riveting tool and appropriate nosepiece for 4 mm rivets. Drill or prepare a hole sized to the rivet diameter, ensuring hole edges are clean and free of burrs. Insert the rivet through the components to be joined until the flange bears against the material surface, position the tool over the mandrel, and actuate the tool per the tool manufacturer's instructions until the mandrel snaps and the rivet sets. After installation, verify that the flange is flush and the blind side bulge indicates a proper clinch within the specified grip range.

Recommendations

For reliable joints, confirm combined material thickness falls within the 3.0–5.0 mm grip range and use a tool with the correct nosepiece for 4 mm rivets. When working with softer materials or finishes, consider using protective washers or backing to avoid surface deformation. Store rivets in a dry environment to prevent contamination and ensure consistent performance during batch operations.
