Blind rivet GESIPA 5×20 mm stainless A2 flat round head for 11–15 mm material thickness

Blind rivet GESIPA 5×20 mm stainless A2 flat round head for 11–15 mm material thickness is a blind fastener designed for applications where access is available from only one side. Made from A2 stainless steel, the rivet body and mandrel materials are selected for corrosion resistance and mechanical stability in common industrial and maintenance environments. The flat round head provides a broad bearing surface and a neat finished appearance on the accessible side of the joint.

Advantages

This blind rivet provides a secure, permanent joint suited to materials with a combined thickness of 11–15 mm. Corrosion-resistant A2 stainless construction offers durability in humid or corrosive atmospheres. The flat round head distributes load over a larger area, reducing the risk of pull-through on softer substrates and delivering a consistent, clean finish. The blind installation method enables fastening where the rear side is inaccessible, and the rivet is compatible with standard blind rivet tools sized for 5 mm rivets.

Suitable for

• Joining sheet metal and panels in construction and metalworking
• Automotive body repairs and components where one-sided access is required
• General assembly of enclosures, frames and brackets
• Applications requiring corrosion resistance and vibration-resistant joints

Key specifications

• Rivet diameter: 5 mm
• Rivet length: 20 mm
• Head style: flat round head
• Material: A2 (stainless) steel
• Recommended combined material thickness: 11–15 mm
• Suitable for blind (one-sided) installation

How to use

Prepare the components by aligning the holes and selecting a 5 mm drill bit for a snug fit. Insert the rivet into the assembled parts until the head sits flush on the accessible surface. Use a blind rivet gun compatible with 5 mm rivets, position the tool over the mandrel, and actuate the tool according to the manufacturer’s instructions until the mandrel breaks off and a proper bulbed clinch forms on the blind side. Inspect the formed blind head to ensure a secure compression of the joined materials.

Recommendations

Drill hole diameter should match the rivet diameter to avoid play; verify the combined material thickness falls within the 11–15 mm range. Use appropriate eye and hand protection when operating blind rivet tools and discard used mandrel fragments safely. For higher corrosion resistance requirements or contact with aggressive media, evaluate compatibility of A2 stainless with the specific environment before installation.
