Customer Reviews

I love how quickly you always ship my orders. The person I spoke to was knowledgeable and helpful.
Very fast response to RFQ (less than 1 day) very competitive pricing and low MOQ requirements
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.
Small order but all was in stock, sales rep was very friendly and made it a pleasure. Shipped and received quicker than expected.
