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!

I've been buying from Military Fasteners for about 2 years. In that time, I don't ever recall having a bad experience. Please keep up the great work and continue offering the fair prices, fast shipping and excellent customer service.
