Blind rivet GESIPA Polygrip 4.8x10 Al/St large flange for 0.5–6.5 mm materials, pack of 250

GESIPA Polygrip blind rivets 4.8x10 mm with a large flange (Al/St) are fasteners designed to join two or more panels when access is available from one side only. These blind rivets accommodate total material thicknesses from 0.5 to 6.5 mm and are supplied in a pack of 250. Constructed with an aluminum body and a steel mandrel, they provide consistent setting performance and resistance to vibration in assemblies made from metal, composites and thin sheet materials used in construction, HVAC, automotive and industrial maintenance.

Advantages

Large-flange head design increases bearing surface and reduces the risk of pull-through on softer or thinner materials. The aluminum body reduces weight and corrosion exposure at the joint while the steel mandrel ensures secure clinching and reliable blind-side expansion. Supplied in a bulk pack of 250, these rivets are convenient for repetitive installation tasks and on-site stocking.

Suitable for (tasks / use cases)

• Joining thin metal sheets and lightweight panels
• Installation of HVAC ducts and metalwork
• Automotive bodywork repairs and assembly
• Industrial maintenance where access is limited to one side
• Composite panel fastening and cladding attachment

Key specifications

• Rivet diameter: 4.8 mm
• Rivet length: 10 mm
• Material combination: aluminum body, steel mandrel
• Head type: large flange (increased bearing surface)
• Recommended total material thickness: 0.5–6.5 mm
• Package quantity: 250 pieces

How to use

Select a rivet diameter and length appropriate for the combined thickness of the materials to be joined. Drill or prepare a hole matching the rivet diameter, insert the rivet through the aligned parts, and position the flange against the visible face. Use a suitable blind-rivet tool to pull the mandrel until the body deforms and clamps the joint; the mandrel will break off when the correct setting force is reached. Verify that the rivet head sits flush and that the blind-side formation provides a secure grip.

Recommendations

For optimal performance, ensure hole diameter and material thickness fall within the specified range (0.5–6.5 mm). When fastening softer substrates, consider the large flange orientation to distribute load and reduce pull-through. Store rivets in a dry place to avoid contamination, and use a rivet tool compatible with 4.8 mm diameter rivets to achieve consistent installation quality.
