Called Military Fasteners for assistance to determine pricing for some material. Ashleigh S. was very nice to work with. Her attitude and happy approach was great. She provided guidance along with a quote for future reference!! Thank you!

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.

I have always turned to Military Fasteners for all my aviation needs. They have never let me down and are totally trustworthy, fast and efficient. They have great choices from reasonably priced, to the best available. I've never seen the need to look anywhere else..Why would I..

I needed a voltage regulator as soon as possible to get a school plane back up. I wasnt able to call in the order until right at the cut-off time. I asked to PLEASE try to get the order shipped that day, and she did. Thank you very much!!
