Patent number: 10926316Abstract: A method and system for installing a fastener system. A collar in the fastener system is automatically positioned on a hole on a first side of a structure prior to an insertion of a pin in the fastener system into the hole from a second side of the structure in which the pin has a pin tail. The pin with the pin tail is inserted through the collar in which the pin extends through the hole and the collar. A force is applied on at least one of the collar or the pin tail along a centerline extending centrally though the collar until the pin tail becomes separated from the pin such that the collar engages an engagement feature on the pin when the pin with pin tail is inserted into the hole from the second side.Type: GrantFiled: March 16, 2018Date of Patent: February 23, 2021Assignee: The Boeing CompanyInventors: Kwok Tung Chan, Tanni Sisco, Eric M.
