TRI-FOLD® blind rivet forms three press lashes on the closing head side during setting. 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. hanks to its special design, the TRI-FOLD® is also able to compensate over-dimensional or irregular drill hole diameters. RI-FOLD® blind rivets are excellently suited for the automotive field, e.g. for plastic panelling, car body parts and for the in-terior work inside vehicles, but also for all other applications that are particularly soft, brittle, easily deformed or porous.
