Trisha Hawkins provided exceptional customer service and went above and beyond to ensure I found exactly what I needed. The quality of the fasteners is top-notch and the delivery was prompt. I highly recommend Military Fasteners for their outstanding products and excellent service. Thank you, Trisha, for making the process so smooth and efficient!

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.
