Great service and lead time. Ships to Canada as well.

When I need parts or products for my aircraft, I think only of Military Fasteners! Dependably in stock, same day shipping and quality, caring employees are all literally guaranteed. I wish every vendor I deal with was anywhere close to being as consistently customer focused!

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!

Props to my saleslady (whose name I have sadly forgotten) for her can do attitude. Fast and efficient yet friendly and thorough. The items arrived nicely padded with brown paper. Im so happy youve stopped using those hard-to-dispose-of styrofoam peanuts. Fast to ship reasonable prices. Just excellent all around!
