A fastener system for multi-piece swage type fasteners, including a pin and a collar, and providing a stump type fastener constructed to be set as a pull type fastener with the fastener pin having a threaded gripping portion and including an installation tool having a swage anvil and a rotary nut member adapted to be threaded onto the threaded pull portion of the pin whereby a relative axial force is applied between the pin and the collar via the nut member and swage anvil to cause the anvil to radially overengage the collar to swage it into locking grooves on the pin and the pull portion remaining on the pin after installation.
La présente invention a pour objet un système de fixation pour organes d'assemblage à éléments multiples de type à sertissage comportant une goupille et un collet ainsi qu'un élément d'assemblage à ergot destiné à servir d'élément de fixation à extraction par traction, la goupille de fixation comportant une partie de préhension filetée; un outil de fixation est également visé comportant une enclume de sertissage ainsi qu'un écrou en translation sur la partie de préhension filetée de la goupille de fixation; l'application d'une force axiale relative entre la goupille et le collier par l'intermédiaire de l'écrou et de l'enclume de sertissage produit le déplacement radial du collier vers les rainures de verrouillage de la goupille, la partie de préhension demeurant sur la goupille après la mise en place du système de préhension.
