Never had any problem since I began ordering from Military Fasteners for some time now! Always got what I ordered :)

I recently had the pleasure of working with Military Fasteners and I couldn't be more satisfied with the experience. Trisha Hawkins provided exceptional customer service and went above and beyond to ensure I found exactly what I needed. The quality of the fasteners is top-notch and the delivery was prompt. I highly recommend Military Fasteners for their outstanding products and excellent service. Thank you, Trisha, for making the process so smooth and efficient!

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.
