Phone was answered on the second ring. The order was taken. All requested items were in stock. Got my order delivered to my door 2 days later.

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.

Lindsey is our go to person at Military Fasteners. When we need a quote she is the first person we look to. We are very happy with the service and product. Highly recommend to others.
