  • Patent number: 5417529
    Abstract: There is disclosed an aerospace fastener system in which a threaded bolt fastener is secured with a free spinning threaded nut or collar and in which the engagement of the threaded members is fixedly secured by an adhesive. In this invention, the length of the bolt fastener is preselected such that when the fastener is applied in a maximum grip condition, the end of the bolt fastener does not project beyond the top surface of the nut or collar. In this invention, the bolt fastener can even be slightly shorter than the length necessary to reach the top surface of the nut or collar when the fastener still meets the tensile load requirement of the specific application. Preferably the adhesive also includes an ultra-violet light fluorescent pigment so that upon ultra-violet illumination, the correct application of the fastener can be easily observed.
