I just ordered four very tiny items for a couple of bucks and you treated me like I ordered much much more. The order got to me in just a few days and all I can say is your company is at the top of my list. Thank you very much. Stan

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!

4.0

I just want to say that I am really liking what is going on with Military Fasteners. The prices, the availability of items, the fast shipping. I really like the ease of ordering online. I have been to so many websites that are confusing to say the least, but yours is easy easy to use, clear and simple. I love being able to look up all my past orders and print out the invoices if need be. I am just thoroughly impressed with everything about Military Fasteners. Keep it up and you will always be on my bookmarks bar in the number one position!

I have been restoring a 1946 Globe Swift over the past year and have relied heavily on Military Fasteners to supply both AN hardware and some aircraft specific parts. The service has been excellent, the expertise in answering some of my questions invaluable. Military Fasteners is my go-to for all my aircraft needs. Thank you all very much.
