Usage
Designed for secure fastening of sheet metal, plastic, or composite components, these large-head rivets are ideal for construction, automotive repair, HVAC assembly, and general metalworking applications where a wide clamp area and high strength are required.
Advantages
- Large 12 mm flange provides increased load distribution and improved pull-through resistance.
- High-strength aluminium alloy body combined with zinc-plated steel mandrel ensures reliable performance in demanding conditions.
- Quick installation with standard blind riveting tools; suitable for single-sided access points.
- Permanently joins dissimilar materials such as aluminium to steel without risk of corrosion between joined pieces.
- The wide head covers oversized or irregular holes and is especially suited for soft or thin materials.
Specifications
- Material: Rivet body from aluminium alloy (AlMg3); mandrel made from zinc-plated steel
- Complies with DIN EN ISO14589 standards for blind rivets; quality assured by GESIPA production processes
- Main dimensions: Ø4 mm shank × 20 mm length; head diameter: 12.0 mm; grip range (material thickness): see application chart per length variant
- Tensile strength: up to 2000 N; shear strength: up to 1400 N; suitable hole diameter: approx. Ø4.1 mm[1][9]
How it works
To use the rivet, insert it into a pre-drilled hole aligning all layers to be joined. A compatible rivet plier pulls the steel mandrel through the aluminium body until the head flares against the surface and clamps all materials tightly together. The mandrel then snaps off automatically at its break point.
