Blind rivet GESIPA VA A2 3×10 mm for 5–6.5 mm Flachrundkopf

Blind rivet GESIPA VA A2 3×10 mm for 5–6.5 mm Flachrundkopf is a single-shear, pull-type stainless steel fastener designed for permanent joining when access is available from one side only. Constructed from A2 stainless steel, the rivet body and mandrel deliver corrosion resistance and consistent clamp force for thin sheets, overlapping panels and assemblies where a Flachrundkopf (flat round head) hole of 5–6.5 mm is specified. The rivet expands and forms a secure blind-side head to create a durable mechanical joint suitable for metal, plastic and composite materials in construction, automotive and general repair applications.

Advantages

The A2 stainless steel construction provides good corrosion resistance in normal outdoor and indoor environments, reducing the need for surface treatments. The pull-type installation creates a reliable, vibration-resistant joint with uniform clamping across the workpieces. Designed for a 5–6.5 mm Flachrundkopf hole, the 3×10 mm size offers precise fit and consistent setting behavior, minimizing deformation of thin materials. The blind installation allows fastening where rear access is restricted.

Suitable for (tasks / use cases)

• Joining thin metal sheets and panels
• Securing plastic or composite assemblies
• Fastening in automotive body repairs and trim work
• Structural and non-structural connections in building and facade elements
• Maintenance and repair tasks where only one-side access is available

Key specifications

• Material: A2 stainless steel (body and mandrel)
• Rivet dimensions: 3 mm body diameter × 10 mm length
• Recommended hole type and diameter: Flachrundkopf hole, 5–6.5 mm
• Installation type: Blind (pull) rivet suitable for single-side access
• Application materials: metal, plastic, composites

How to use

Drill a correctly sized Flachrundkopf hole of 5–6.5 mm through the assembled parts. Insert the blind rivet through the hole until the head rests flush against the visible surface. Use an appropriate blind rivet tool or rivet gun matched to the rivet diameter to pull the mandrel; continue pulling until the mandrel snaps and the blind-side sleeve forms a secure head. After setting, remove the spent mandrel remnants if necessary and inspect the joint to ensure full clamping and correct formation of the blind-side head.

Recommendations

Use corrosion-compatible materials for mating parts to avoid galvanic corrosion. Select a rivet tool calibrated for 3 mm stainless rivets and apply steady pulling pressure to achieve consistent setting. For critical or load-bearing joints verify clamp thickness and shear requirements; pre-drill accurately to maintain head seating and minimize material distortion.
