I sent in my online order then within a minute I realized I left off an item. I sent a message that requested an item be added to avoid a second shipping cost. I received a reply the next morning that the item I wanted had been added successfully and my order would be delivered as promised. Thanks to your staff for the flexibility and the help with my online order.

Ive been purchasing aircraft parts and hardware from Military Fasteners for over 4 years. That alone should speak volumes. Ive always received excellent customer service and the product quality is unrivaled. When I think of aircraft parts and accessories, Im thinking Military Fasteners. Keep up the excellent work folks! Regards, Ed

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.
