Features: Gesipa Blind Rivet Nuts: Simple, yet clever. GESIPA® blind rivet nuts are fasteners that create strong and highly load-bearing threads for a removable connection. Blind rivet nuts represent an internal thread. Just like a blind rivet, two or more components can be connected with both fasteners. A blind rivet nut is essentially a threaded hollow rivet. It can be installed blind, meaning with access from only one side, into a workpiece. This simplicity is what makes the blind rivet nut so smart. Gesipa offers blind rivet nuts in various designs with different setting head shapes and made from various materials such as aluminum, steel, or stainless steel. Particularly flexible is the PolyGrip blind rivet nut, which can bridge an extremely large clamping range, significantly reducing the variety of parts in production. Threads? Absolutely! A blind rivet nut can create secure and load-bearing threads in workpieces, even in very thin-walled and soft materials. Additional parts can then be easily screwed onto these threads. In principle, it is also possible to rivet materials followed by screwing. The blind rivet nut is ideally suited for creating threads in hollow profiles. Features: AlMg3.
