I can say that Military Fasteners was able to deliver the part to me very quickly. I live in a very remote area in the Tennessee mountains and typically have to wait up to two weeks to receive deliveries. Sometimes, the delivery guys cannot find my house at all, and they have to leave my packages at the local general store. But with Military Fasteners, my packages always find my front door step and in great condition. This package arrived nearly a week earlier than expected, and that was over the New Years holiday! Great work, Military Fasteners, on your delivery service. Thanks!

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.
