5J21 blind rivets in aluminium alloy deliver reliable fastening for lightweight structural applications. These open-end rivets feature a 4.0mm diameter and 12mm length, engineered for precision assembly where weight reduction matters. The aluminium construction resists corrosion, making them ideal for automotive, aerospace, and general fabrication work. The blind rivet design allows installation from one side, eliminating the need for access to both surfaces. Suitable for sheet metal, composites, and thin-walled components requiring durable, permanent joints.
