HYBRID FASTENING SYSTEM AND ASSOCIATED METHOD OF FASTENING

摘要

A hybrid fastening system comprising a female fastener component, i.e., swage collar (30), fabricated from a titanium or titanium-alloy material, preferably Ti-3A1-2.5V, and a mating titanium or titanium-alloy material male fastener component, i.e., threaded pin (40), each preferably pre-coated with an organic coating material comprising an organic, phenolic resin. The threaded pin component (40) is installed through two or more structural components (10, 20) to be joined. The swage collar component (30) is then deformed or swaged onto the threads of the pre-coated threaded pin component (40) to achieve the same, if not improved, fastener/joint performance characteristics of existing lockbolt systems using aluminum-alloy material swage collar components.
