  • Patent number: 4720223
    Abstract: The present invention provides a self-retracting, captive fastener assembly which allows the application of a controlled preload not requiring separate measurement during or after application. The assembly includes the use of a hold-out spring (31) which is isolated and fully retracts the assembly when the installed assembly is not engaged with a substructure. A housing (32) is provided for the hold-out spring (31) and contains the spring (31) when it is fully compressed. For the controlled preload, disc springs (40) are used. The shoulder (60) of the bolt shank portion (24) is staked so as to form protrusions (61,62,63,64) for captivating these mentioned elements upon the bolt. A removable, retaining element or stop-nut (50) is also provided for securement of the fastener to a first structure 65. The stop-nut (50) is constructed so that it must be seated against substructure (70) in order to achieve the controlled deflection of the disc springs (40) and thereby achieve the desired preload application.
