I have been doing business with Military Fasteners for a number of years. Every Time I have needed a question answered in finding something for my projects Military Fasteners has always been there. The people I talk to are helpful and knowledgeable concerning all the vintage planes I have called looking for a special item needed. Thank you for being YOU!

The only hardware supplier that rushes to ship your order. Placed an order at 4pm, and they got it out same day.

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.
