I have been satisfied overall with the service I get from Military Fasteners. I have never had an issue with any of my orders, they have been prompt and fulfilled error free.

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.

Products are military grade MIL-SPEC as advertised. I was able to locate #10 locking counter-sunk nutplates when ALL other locations, including Aircraft-Spruce, could not supply.

I am always impressed that you can process and ship and order only a few hours after you get it. Keep up the good work.
