I have built an airplane with parts from Military Fasteners. In the last years I have only had one issue involving warranty problems and that was resolved by the factory. Good service and quality parts/availability are very good at Military Fasteners.

I order parts about once a week for the restoration of my Grumman AA-1A. Service and prompt delivery are always above expectation. I don't know what I would do without Military Fasteners and that's no joke! Thanks for your great work!
