Blind rivet GESIPA 1454030 4x16 mm Al/St for 10.5–12.5 mm panels, pack of 500

Blind rivet GESIPA 4x16 mm Al/St is a single-sided fastening element designed for joining panels and thin sheets where access to the rear side of the assembly is restricted. The rivet has an aluminium body and a steel mandrel, engineered to create a reliable clinch in materials with a combined thickness suitable for 10.5–12.5 mm. Supplied in a pack of 500, this fastening solution is intended for repetitive installation tasks in metal, composite and sheet applications.

Advantages

The aluminium body provides corrosion-resistant bearing on the material surface while the steel mandrel ensures consistent blind-side expansion and high clamp strength. The 4×16 mm size is optimized for panel thicknesses in the 10.5–12.5 mm range, delivering predictable grip and joint integrity. Packaged as 500 pieces, the set reduces downtime for replenishment on production lines or installation sites.

Suitable for

• Single-sided assembly of metal and aluminium panels
• Joining composite boards and sandwich panels
• Sheet metal work where back access is limited
• Industrial and construction panel installations

Key specifications

• Rivet diameter and length: 4 × 16 mm
• Body material: aluminium
• Mandrel material: steel
• Recommended total material thickness: 10.5–12.5 mm
• Packed quantity: 500 pieces

How to use

Drill a hole with the correct 4 mm diameter through the joined materials, ensuring alignment of panels. Insert the blind rivet through the hole until the head sits flush against the surface. Using a suitable blind rivet tool, pull the mandrel until the mandrel breaks and the aluminium body forms a blind-side bulge, creating a secure clamp. Verify the rivet head sits evenly and the joint has sufficient compression across the panel thickness. Remove any swarf or debris after installation.

Usage recommendations

Use a rivet gun rated for steel-mandrel blind rivets and maintain consistent pulling force for repeatable results. For corrosion-sensitive assemblies, ensure both panel materials and rivets are compatible; consider isolation or sealing if dissimilar metals are in contact. Store the pack in a dry environment to prevent contamination and inspect rivets before use for straight mandrels and undamaged heads.
