Customer Reviews

Had an order discrepancy. Kristen Belmont to the rescue! Very well taken care of. Thanks to Military Fasteners for having a wonderful C.A.R.E team!
I was impressed with the speedy delivery of my order and also with the order itself.
Very fast delivery and always getting what I ordered. Never had an issue with the few returns I've had. They have been very friendly and helpful.
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.
