Usage
Rivets standards alu / acier tête large K12 GESIPA Ø4x12mm are designed for permanent fastening of metal sheets, profiles, or components where a wide load-bearing surface and strong mechanical hold are required. Suitable for industrial assembly and repair.
Advantages
- Combines lightweight aluminium body with robust steel mandrel for reliable performance.
- Large flange head increases bearing surface to prevent pull-through on soft or thin materials.
- Conforms to DIN EN ISO 14589/ISO 15977, ensuring consistent quality and compatibility.
- Zinc-plated mandrel provides improved corrosion resistance in demanding environments.
- A minor drawback: not suitable for applications requiring watertight joints without additional sealing measures.
Specifications
- Design: Hollow aluminium alloy rivet body with zinc-plated steel breakstem; large flange (K12) head type.
- Covers a clamping range from minimum 6.5 mm to maximum 8.5 mm material thickness per DIN EN ISO standards.
- Main dimensions: Body diameter Ø4 mm, length of rivet body is 12 mm; hole diameter required is approximately Ø4.1 mm; head (flange) diameter is approx. Ø12 mm.
- Tensile strength up to approximately 1,400 N; shear strength rated at around the same value for durable fastening in metalworking and construction projects.
How it works
The rivet is inserted into a pre-drilled hole through the materials being joined. Using compatible rivet pliers, compression deforms the internal mandrel which expands the blind side of the rivet behind the workpiece, securely locking all layers together.
