GESIPA rivetto cieco acciaio/acciaio 4x8mm testa tonda piatta campo di serraggio 2,5-4,5mm (6310443)

Blind rivet for permanent fastening in metalworking and sheet metal applications. The steel body and steel mandrel provide high shear and tensile strength for load-bearing joints. The dome head (Flachrundkopf) sits flush on the material surface and distributes clamping force evenly. With a grip range of 2.5 to 4.5 mm, this rivet covers a wide range of material thicknesses in a single size, reducing the need for multiple rivet lengths on a job.

Advantages

Steel/steel construction offers excellent vibration resistance and prevents loosening in dynamic applications. The dome head profile is suitable for both functional and visible joints. Installation is quick with any standard blind riveting tool, and the rivet creates a vibration-proof, tamper-resistant connection.

Suitable for

• Sheet metal fabrication and enclosures
• Automotive body and chassis components
• HVAC ductwork and ventilation systems
• General metalworking and maintenance
