Customer Reviews

Ive been purchasing aircraft parts and hardware from Military Fasteners for over 4 years. That alone should speak volumes. Ive always received excellent customer service and the product quality is unrivaled. When I think of aircraft parts and accessories, Im thinking Military Fasteners. Keep up the excellent work folks! Regards, Ed
I have been a regular customer of military fasteners since 2018. I have always been satisfied with my purchases and quality of product.
Great company!! Devin B attention to detail and friendliness made all the difference
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.
