TRI-FOLD folding Type blind rivets – for soft and porous application materials The function The GESIPA TRI-FOLD blind rivet forms three press lashes on the closing head side during setting. Tthe advantages The large moulded lashes distribute the exerted clamping force evenly and gently onto the riveted material. Also, the large surface of the lashes offer excellent protection against the rivet being pulled through very soft, porous or brittle application parts. Thanks to its special design, the TRI-FOLD is also able to compensate over-dimensional or irregular drill hole diameters. Application areas TRI-FOLD blind rivets are excellently suited for the automotive field, e.g. for plastic panelling, car body parts and for the interior work inside vehicles, but also for all other applications that are particularly soft, brittle, easily deformed or porous.
