The order was complete and arrived by mail in short order. The staff who took my order was very helpful and answered my questions. Very pleased, thanks to military fasteners

5.0

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.

Excellent service, as always and the reason I buy all my aviation parts from Military Fasteners!

I would not change a thing. You folks have always supplied me with what I needed if you have it in stock (nobody has everything). Delivery has always been good. I am glad you now have a store in Georgia since I live in FL. Makes things a lot easier and quicker than getting stuff from California. Keep up the good work. I have a few more things to order in the next few days too. Thanks.
