Brittany was attentive to our needs. We had to source some other products you didn't have elsewhere. We would have preferred to place an order a one place. Will come back and order another time.

Great service, I run a small GA workshop and I can count on Military Fasteners even though I'm in Australia, its quicker than getting it in Australia most of the time. The web site is great and simple to find the parts needed.
