Customer Reviews

Fast delivery, excellent choice on product that covers all types of aircraft. This range of product makes it easy to rebuild and maintenance your aircraft.
Order was filled perfectly. I know I can rely on Military Fasteners.
Very pleased with the customer service I get when I call. My Cessna 182 is always needing a little bit of extra LOVE from Military Fasteners. When I call to order parts, your training and customer service of your order takers are the tops.. They understand what I'm looking for and can help me figure out how to order it. I've upgraded my old normal headsets to your reconditioned Bose X General Aviation Noise Cancelling. These are my first Noise Cancelling headsets and we are very pleased...I've come back and purchased 2 more...You are a very professional group! With your shipping location in Atlanta, sometimes, I get things in 1 day or 2 at the most. Thanks.
As expected, fast and accurate service with products at a fair price.
