Blind rivet, combined, large flange

The combined blind rivet with large flange is used for permanent joints in thin-sheet metal and replaces a weld seam where access to the joint is limited. The thickness of the joined sheets ranges from 1.5 to 45 mm, depending on the mandrel length and flange diameter.

The rivet body is made of copper, pure aluminium or an aluminium alloy with up to 2.5% magnesium content (Al(Mg2.5%)). The mandrel is made of stainless steel (A2) or alloy steel (St). Rivets are installed using a rivet gun.
