When recently ordering some barry engine mounts I found your site carried excellent technical information and the whole process went smoothly and efficiently and I was very surprised to receive the goods in question so quickly.

I have dealt with Military Fasteners a few times and they have always been extremely helpful and knowledgeable. Ramona has always been wonderful to work with and goes out of her way to help you find what you need. Definitely recommended!

It is always a pleasure ordering from Military Fasteners. You can talk to a real, live, human being who is helpful and courteous thru the whole process. I received my order on time and as promised. Military Fasteners is my Go To place for all aviation supplies.

Tanks for the fantastic service. I ordered over the new year period and was amazed my shipment arrived so fast, all the way to New Zealand. Less than a week and that included clearing Customs. Awesome!!
