Customer Reviews

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.
Have been buying from you for many years and have been very very satisfied.
Military Fasteners is a great resource for Mil-Spec fastener needs, and Amelia Fato provides excellent support! Whenever I have a specific need, Amelia is quick to respond and help!
To say I am satisfied with all purchases from Military Fasteners is a bit of an understatement. Selection, price, packaging, shipping exceeds expectations. You are my number one choice for my aircraft needs, thank you, Charles
