Blind rivet GESIPA 6310141 Steel/Steel 3×8 mm flat head for 3.0–5.0 mm materials

Blind rivet GESIPA 6310141 is a steel-body, steel-mandrel fastener with a flat head measuring 3×8 mm, engineered to join materials with a combined thickness of 3.0–5.0 mm. Designed for blind, one-sided installation, this rivet provides a permanent, vibration-resistant joint where access to the far side of the workpiece is limited or impossible. Common applications include sheet metal assemblies, enclosures, frames and general metal fabrication requiring a flush, low-profile head.

Advantages

This steel/steel blind rivet offers consistent clamping and high shear strength suitable for metallic joins. The flat head provides a neat, low-profile finish on the visible side and distributes load evenly. Its blind installation capability reduces assembly time and allows fastening in confined or enclosed structures. Made from steel materials, the rivet is compatible with a range of common metal substrates and delivers reliable mechanical performance in standard industrial and construction environments.

Suitable for

• Joining sheet metal panels and plates
• Securing enclosures and cabinets
• Frame and chassis assembly in metal fabrication
• Repairs and retrofits where only one side is accessible

Key specifications

• Body material: steel
• Mandrel material: steel
• Head type: flat (countersunk/low-profile appearance)
• Head dimensions: 3×8 mm
• Suitable grip range (total material thickness): 3.0–5.0 mm
• Installation method: blind (one-sided) riveting

How to use

Drill a hole matching the rivet diameter in the assembled parts, ensuring proper alignment of components. Insert the rivet through the hole from the accessible side so the flat head sits flush against the material surface. Use a compatible blind rivet tool or pneumatic/hydraulic rivet gun designed for steel rivets; engage the mandrel and actuate the tool until the mandrel snaps, forming the blind-side bulbed head that secures the joint. Remove the spent mandrel and inspect the riveted joint for proper grip and head seating.

Recommendations

For best results, select a drill diameter that matches the rivet body and verify the combined material thickness is within the 3.0–5.0 mm range. Use corrosion-appropriate measures (such as coatings or sealants) when joining dissimilar metals or when environmental exposure is expected. Choose rivet tools rated for steel mandrels to ensure consistent setting and avoid tool wear.
