Rebite cego GESIPA PolyGrip® 4,8×10,0 mm alumínio/aço inoxidável, pack de 50

Blind rivet GESIPA PolyGrip® 4.8×10.0 mm Aluminium/Stainless steel, pack of 50 is a blind-side fastening element combining an aluminium body with a stainless steel mandrel. Designed for joining thin sheet materials and mixed-material assemblies, this rivet creates permanent, vibration-resistant joints when installed from one side. The pack of 50 provides a practical quantity for repair, maintenance and small to medium production runs where blind installation is required.

Advantages

The aluminium body ensures low weight and good corrosion resistance while the stainless steel mandrel provides high shear and tensile strength at the break point. The blind installation design allows fastening where rear access is restricted, and the PolyGrip® system provides consistent flange formation and reliable clamp range performance. Supplied in a bulk pack of 50, these rivets reduce changeover frequency and simplify inventory management for workshops and service teams.

Suitable for

• Assembly of thin sheet metal panels
• Mixed material joints (e.g., aluminium to steel)
• Automotive bodywork repair and trim fastening
• Construction and HVAC installations with restricted access
• Industrial equipment maintenance and enclosure assembly

How to use

Select a compatible blind rivet tool sized for 4.8 mm diameter rivets, position the rivet through the prepared hole in the workpieces, and insert the mandrel into the rivet tool nosepiece. Squeeze or actuate the tool according to the manufacturer's instructions until the mandrel snaps, forming the blind-side bulge and clamping the workpieces. Remove the spent mandrel from the tool and inspect the formed head and break-off point to ensure a secure joint. Use correct nosepiece and setting parameters to achieve consistent results.

Recommendations

For best results, pre-drill holes to the recommended diameter, use a rivet tool compatible with 4.8 mm PolyGrip® rivets, and choose rivet placement that avoids excessive edge distance or overlapping with high-stress areas. When joining dissimilar metals, consider insulating coatings or washers to reduce galvanic corrosion in long-term outdoor applications.
