We have been dealing with Military Fasteners and have always found them professional in their approach and happy to assist with any problems we may face in this ever changing industry. The parts ordered are those received, prices quoted are those we pay, the delivery times are acceptable considering we are on the other side of the world and should we require non listed stock we are advised where such stock may be procured. Thank you for your service over those years and we look forward to maintaining our relationship well into the future.

Military Fasteners is my go-to on-line place for aviation items. I do most of my ordering from your web site, but when I can't work out exactly what I want, your sales agents have been extremely helpful.

You all are Awesome! I am restoring a 1946 all aluminum camper and have come to you several times for materials needed. Every time I order, I get a quality product at a fair price in a timely manner. I couldn't ask for more.
