Ashili Hansen was very helpful.

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.

Recently my avionics technician and I were installing a component in my aircraft and there were some critical fasteners missing from the manufactures package. This stopped the entire process. I called Military Fasteners after finding the parts on line, and Trisha answered the phone. I told her the situation and that I needed them ASAP. I found the parts gave her the part number and she confirmed they were in stock. This was about 430 in the afternoon just before closing. Trisha was kind and professional got the parts out the door that evening even though it was after the shipping cut off. Saved the day. I can tell you this entire company is represented by Trisha, anything they can do to help you out of a jamb they will absolutely go the extra mile and Trisha is the go to person. I am sure there are others there with her same attitude and professionalism. This is a great resource for all your fasteners needs.
