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.

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.

Hello, I am an Estimator for CAMCO Mfg. Inc. We work with many Prime companies that require Military Fasteners. Kristen Belmont is always the first to respond and gives me great service! She guides me with her knowledge and treats me w/much respect (even when I don't know what I'm talking about) Out of all the outside sources I have to work with, I enjoy working with her best!
