Patent number: 11353054Abstract: The invention relates to a positive locking fastener comprising: a screw (1) having a cavity (110) at a threaded portion (11); a nut (2) having a tightening portion (21); a first cap (3); a second cap (4); and a pin (5). The first cap is suitable for being inserted into the cavity of the threaded portion. The second cap has a locking portion (402) intended to engage with the first cap and a blocking portion (401) intended to engage with a tightening portion (21) of the nut. The locking portion of said second cap comprises openings (4020) suitable for allowing the pin to be inserted through said openings in order to hold the first cap and the second cap together. The invention also relates to a method for implementing the fastener according to the invention.Type: GrantFiled: June 14, 2018Date of Patent: June 7, 2022Assignee: LISI AEROSPACEInventors: Julien Goyer, Mohamed Abou Halima, Loïc Meiffre
