## Summary description

GESIPA Polygrip blind rivets, size 4.8×25 mm, aluminium body with steel mandrel (Al/St). Designed for blind (one-sided) fastening where access is available only from one side.

Suitable for joining metal sheets, profiles and assemblies in construction, HVAC, automotive and general fabrication for secure, vibration-resistant joints.

## Long description

GESIPA Polygrip blind rivets 4.8×25 Al/St are one-sided fasteners with an aluminium body and a steel mandrel, designed for creating permanent, vibration-resistant joints where access is available only from one side. Each rivet measures 4.8 mm in diameter and 25 mm in length, and the specified grip range of 11.0–19.5 mm allows fastening of medium-thickness materials. Supplied in a pack of 250, these rivets are intended for repetitive use in assembly and construction applications.
Advantages
The aluminium body provides corrosion-resistant clamping while the steel mandrel ensures consistent setting strength and break-off performance. The blind installation capability simplifies assembly when the rear side of the workpiece is inaccessible. A wide grip range reduces the need to stock multiple rivet lengths and the 4.8 mm diameter offers a balance between shear and tensile strength suitable for many sheet metal and profile connections.
Suitable for
 Joining metal sheets and profiles in building and construction
 HVAC ductwork assembly and mounting brackets
 Automotive interior and body repairs where one-sided access is required
 General fabrication and installations requiring vibration-resistant joints
Key specifications
 Rivet diameter: 4.8 mm
 Rivet length: 25 mm
 Body material: aluminium
 Mandrel material: steel
 Grip range: 11.0–19.5 mm
 Pack quantity: 250 pieces
How to use
Drill a hole matching the rivet diameter through the workpieces and insert the rivet so the flange sits flush against the surface. Use a compatible blind rivet tool or riveter sized for 4.8 mm rivets to pull the mandrel until it breaks off, forming the blind head and clamping the materials together. Ensure the tool is set to the correct stroke and pull force for Al/St rivets to achieve proper mandrel breakage and consistent joint formation.
Usage recommendations
For best results, select a drill hole tolerance that matches the rivet diameter, clean mating surfaces from debris and paint in the joint area, and check material thickness to confirm the grip range covers the total stack. When fastening dissimilar metals, consider surface treatments or isolation to reduce galvanic corrosion over time.
