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.

Your staff is courteous and well informed about your product line. Your inventory is excellent and competitively priced. The shipment always arrives as advertized and the boxes are well packed. I will continue to order my aircraft supplies from 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.

In this day and age, it is rare to be impressed by customer service however, Military Fasteners has far exceeded my expectations. They went above and beyond to help ensure an important package delivery on time, and they made a little boys Christmas sweeter in the process. Thank you to the team there for your wonderful help. I will certainly come back to shop again and again. They always say, fly people are the best people.
