I placed an order with Lindsey at Military Fasteners late afternoon, 3:15 to be exact and she was nice enough to expedite my order and made sure to get it shipped that day. Great company with great people.

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.

Have had nothing but great experiences. If I ever need anything I just email Amelia Fato and she gets me fixed up! Super fast and helpful customer service. 10 out of 10.

Dependable! I KNOW that my orders with military fasteners will go out the same day and that the rare backorder will be shipped without my having to follow up.
