GTRERIV-Blind rivet Alu/Alu+gasket gr 1,5-6,4 DH 4,0x20,3

Aluminium body with washer.
Aluminium mandrel.
Dome head.
Mainly used to fix photovoltaic panels brackets on corrugated sheet metal and sandwich panels.
Excellent grip force
The three legs along the nail of the rivet collapse to grip the mounting surface, unlike the Fioriv, the legs close on themselves just like a packet, increasing the structural strength. Three big pression legs distribute the tightening force evenly over a wide area of the surface. Soft, thin, flexible or fragile materials can be riveted safely as well without destroying or damaging the surface.
Excellent weather resistance thanks to the integrated seal.
To ensure resistance to leakage caused by the rain we recommend:
Hole without burr and shavings.
Well aligned sheet.
Good pressure on the rivet to press the washer firmly.
