I was working with Kasey and she was very helpful. I received our fasteners very fast.

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.

All of my orders have originated thru your online system and have arrived on time as advertised. Your system performs great. I can decide while ordering how I want it shipped and what cost. All things said, I find your system very easy to order thru.
