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.

As a race car owner and builder I find your pricing and selection of AN hardware and composite materials more than meet my needs and expectations.

Great product at a good price, fast delivery. Easy install, fired up perfectly right out of the box.
