Youre team did an excellent job as usual. The sheet metal and grommets arrived in excellent condition and were very well priced which I appreciate. Thanks again. Doug

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.

After an extensive look for parts, Ramona Real of Military Fasteners was the one that could help in finding what I needed and provide the necessary paperwork to go with it. Shipping on time and packing perfect. Good people to work with and highly recommended A+++++
