I am a retired AME/Pilot. I have been restoring a 1946 Globe Swift and have relied on the support and expertise provided by your sales staff. My experience has been very positive. In return, I buy everything I can from Military Fasteners. You are my preferred supplier. Thank you.

Military Fasteners always seems to get the order correct and delivered when expected. I this day and age, this is high praise.

5.0

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.

Your staff is courteous and well informed about your product line. Your inventory is excellent and competitively priced. The shipment always arrives as advertized and the boxes are well packed. I will continue to order my aircraft supplies from military fasteners
