Customer Reviews

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.
In dealing with Military Fasteners for 3 plus years, I can honestly say Ive never had a bad experience with the company. Please keep up the great work and youll keep me coming back for as long as I am flying.
