## Long description

GESIPA Polygrip blind rivets 4.8x25 Al/St with a large flange provide permanent blind fastening where access is available only from one side. Each rivet has a 4.8 mm shank diameter and a 25 mm overall length, offering a grip range of 11.0–19.5 mm. The combination of aluminum body and steel mandrel makes these rivets suitable for joining mixed materials such as metal-to-metal and metal-to-plastic in construction, HVAC, automotive and general industrial repair applications. Supplied in a pack of 100, they are intended for repetitive installation using a compatible blind rivet tool.
Advantages
These large flange blind rivets deliver a wide bearing surface that reduces material pull-through on softer substrates and thin sheets. The aluminum body provides corrosion resistance and lightweight characteristics while the steel mandrel ensures reliable setting and clamp force. The specified grip range covers a broad thickness span, reducing the need to stock multiple sizes for varied assemblies. Supplied in a bulk pack of 100, they support continuous work cycles and workshop operations.
Suitable for
Joining metal sheets and aluminum profiles
Attaching plastic panels to metal frames
HVAC ductwork assembly and repair
Automotive bodywork and interior trim fastening
General industrial maintenance and repair tasks
Key specifications
Shank diameter: 4.8 mm
Overall length: 25 mm
Grip range: 11.0–19.5 mm
Body material: aluminum
Mandrel material: steel
Flange type: large flange
Pack quantity: 100 rivets
How to use
Select the rivet size that matches the combined material thickness within the stated grip range. Drill or prepare a 4.8 mm diameter hole through the components to be joined, insert the rivet so the flange bears against the visible surface, and place the mandrel into a suitable blind rivet tool. Operate the tool according to the manufacturer's instructions until the mandrel breaks and the rivet body forms a blind head, clamping the materials together. Remove any mandrel remnants and check the joint for correct seating and clamp.
Usage recommendations
When fastening softer materials or thin sheets, use the large flange to minimize pull-through. Avoid using these rivets outside the specified grip range to ensure proper blind-head formation and strength. For corrosive or dissimilar-metal environments, consider additional protective measures such as sealants or isolating washers to prevent galvanic corrosion. Use a rivet tool rated for 4.8 mm rivets and inspect tool jaws regularly for wear to maintain consistent installation quality.
