A fastener system for multi-piece swage type fasteners, including a pin (12) and a collar (14), and providing a stump type fastener (10) constructed to be set as a pull type fastener with the fastener pin (12) having a threaded gripping portion (34, 36) and including an installation tool (44) having a swage anvil (50) and a rotary nut member (46) adapted to be threaded onto the threaded pull portion (34, 36) of the pin (12) whereby a relative axial force is applied between the pin (12) and the collar (14) via the nut member (46) and swage anvil (50) to cause the anvil (50) to radially overengage the collar (14) to swage it into locking grooves (32) on the pin (12) and the pull portion (34, 36) remaining on the pin (12) after installation.
Système de fixation pour éléments de fixation multipièces du type à rétreindre, comprenant un axe (12) et un collier (14), et constituant un élément de fixation type moignon (10) conçu pour être placé comme élément de fixation par traction, l'axe (12) possédant une partie de préhension filetée (34, 36), et comprenant également un outil de montage (44) présentant une enclume à rétreindre (50) et un écrou rotatif (46) se vissant sur la partie filetée de traction (34, 36) de l'axe (12). Un effort axial relatif est appliqué entre l'axe (12) et le collier (14) par l'intermédiaire de l'écrou (46) et de l'enclume à rétreindre (50), pour amener cette dernière à passer radialement par dessus le collier (14) afin de le faire pénétrer par rétreinte dans les rainures de verrouillage (32) ménagées sur l'axe (12) et la partie de traction (34, 36) restant sur l'axe (12) après montage.
