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!

Military Fasteners provided the supplies needed to repair my prop. They had the exact items I needed, at a good price. My order was delivered in reasonable time, complete with instructions. The end result was a quality repair to get me back flyin again. Thank you! Steve
