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 a customer since Fullerton Air Parts (Flo Irwin). That should speak volumes of the service I have received from Military Fasteners. In the early days, I had a variety of planes and was based out of Orange County Airport. At the time, the airport was surrounded by bean fields. I, and some of my friends, would frequently fly into Fullerton airport for lunch, the pick up whatever supplies we needed from Flo. She was a great lady, and I am glad that she passed on such a wonderful legacy. I am certain that she would be very proud of what she started, and proud of you all for building on her meager beginnings.
