Sokkiniitti GESIPA 4,0×8,0 mm alumiini/teräs, 500 kpl

Blind rivets GESIPA 4.0×8.0 mm (aluminum body, steel mandrel) in a pack of 500 are engineered for fastening thin materials when access is available from only one side. These blind rivets create a strong, vibration-resistant joint suitable for metal sheets, panels and composite materials. The combination of an aluminum sleeve and a steel mandrel balances corrosion resistance and installation strength, while the 4.0×8.0 mm dimensions correspond to common panel and bracket thicknesses encountered in industrial assembly and maintenance work.

Advantages

The aluminum body provides lightweight corrosion resistance, and the steel mandrel ensures reliable expansion and consistent clamping force during installation. Supplied in a bulk pack of 500, these blind rivets offer cost-effective continuity for production runs and maintenance tasks. Their standardized shape and dimensions make them compatible with most manual and pneumatic blind rivet tools, enabling quick installation and repeatable joint quality.

Suitable for

• Joining thin metal sheets and panels in industrial assembly
• Fastening brackets, trims and cable management components
• Maintenance and repair tasks where only one-sided access is possible
• Lightweight constructions and non-structural assemblies

Key specifications

• Rivet head material: aluminum sleeve with steel mandrel
• Shaft diameter: 4.0 mm
• Shaft length: 8.0 mm
• Head style: blind rivet profile suitable for flush or raised installation depending on tool and countersink
• Pack quantity: 500 pieces
• Typical grip range: appropriate for thin material assemblies (verify with material thickness and tool capability)

How to use

Prepare mating parts by aligning holes with a diameter suitable for a 4.0 mm rivet shaft and ensure edges are clean and free of debris. Insert the rivet through the assembled parts so the mandrel protrudes; place the rivet tool over the mandrel and actuate according to the tool manufacturer’s instructions. The mandrel will pull and form a blind head on the blind side, compressing the sleeve to clamp the materials. After the mandrel breaks off, inspect the rivet for correct setting and secure clamping.

Recommendations

Use a rivet tool compatible with 4.0 mm rivet shafts and follow recommended maintenance for the tool to ensure consistent installation. For materials prone to galvanic corrosion, consider isolation or alternative material combinations. Verify grip range against combined material thickness before series installation.
