Blind rivet GESIPA Polygrip 4.8x10 Al/A2 large flange KS 0.5–6.5 mm, pack of 250

GESIPA Polygrip blind rivets 4.8x10 Al/A2 with a large flange (Grosskopf) KS are designed for permanent blind fastening where an extended bearing surface is required. The rivet features an aluminium body combined with an A2 stainless steel mandrel, providing corrosion resistance on the mandrel and a lightweight aluminium sleeve. The nominal grip range of 0.5–6.5 mm accommodates a variety of sheet thicknesses and component assemblies. Packaged as 250 pieces, this set is suitable for production runs, repair work, or ongoing maintenance.

Advantages

These blind rivets offer a robust and reliable joint with a large flange that distributes load over a wider area, reducing the risk of material pull-through on softer substrates. The aluminium body keeps weight low while the A2 mandrel improves resistance to corrosion in many environments. The specified grip range increases versatility across different panel thicknesses, and the uniform manufacturing tolerances ensure consistent blind-side formation and repeatable clamping force during installation.

Suitable for

• Joining thin metal sheets, aluminium panels and light alloys
• Applications requiring a wide bearing surface to prevent pull-through
• General assembly, maintenance and repair tasks in workshops and production lines
• Enclosures, HVAC ducts, signage and lightweight structural fixings

How to use

Select a rivet with the correct diameter and grip range for the combined thickness of the materials to be joined. Drill a clearance hole of the correct diameter, insert the rivet fully into the hole so the large flange sits flush on the visible surface, and position the rivet gun on the mandrel. Operate the blind rivet tool according to its instructions until the mandrel snaps, forming the blind head and clamping the materials. Remove any mandrel stub if required and inspect the joint for correct flare and compression.

Usage recommendations

Use corrosion-compatible rivets and tools for the application environment; ensure the selected rivet grip range matches total material thickness. For soft or thin materials prefer large-flange rivets like this model to reduce risk of pull-through. Verify hole alignment and cleanliness before installation for best joint integrity.
