Τυφλό πριτσίνι GESIPA 4,8x10 mm Σώμα αλουμινίου Mandrell χάλυβα PolyGrip (MPN 6700144)

Blind rivet GESIPA 4.8x10 mm aluminium body with a steel mandrel in PolyGrip design is a one-sided fastening element for creating durable, permanent joints where access is limited to one side. The 4.8x10 mm size is suitable for light-to-medium assembly tasks and is commonly used to join thin metal sheets, plastic panels, and composite parts. The aluminium body offers corrosion resistance and low weight while the steel mandrel provides controlled break-off and reliable clinching performance.

Advantages

The PolyGrip configuration ensures consistent setting behaviour and reduced mandrel protrusion after installation, resulting in a neat finish on the visible side. The aluminium body combined with a steel mandrel balances strength and weight, allowing secure connections without overloading thin materials. Compatibility with standard blind-riveting tools and the common 4.8 mm diameter make these rivets easy to source and use across many applications.

Suitable for

• Joining thin metal sheets and panels
• Attaching plastic or composite components
• One-sided assembly and maintenance work
• Light-to-medium structural connections in HVAC, enclosures, and fixtures

Key specifications

• Body material: aluminium
• Mandrel material: steel
• Nominal size: 4.8 x 10 mm (diameter x grip length)
• Design: PolyGrip blind rivet
• Connection type: blind (one-sided) fastening

How to use

Select a rivet with appropriate grip range for the combined thickness of the joined materials. Drill an accurately sized hole through the parts to be joined, insert the rivet from the accessible side, and position the rivet flush against the workpiece. Use a compatible blind-riveting tool to pull the mandrel until the aluminium body deforms and clamps the materials together; the mandrel will break off at the specified break point, leaving a finished head on the blind side. Inspect the joint visually to ensure proper set and full contact of the rivet flange with the material surface.

Recommendations

For optimal results, match the rivet length to the material stack thickness and use a rivet gun rated for 4.8 mm rivets. Pre-drilling with the recommended drill size reduces eccentric loading and helps achieve consistent clamping. In corrosive environments, consider material compatibility between the aluminium body, steel mandrel and the joined substrates to avoid galvanic effects.
