I have purchased most of my aviation needs from Military Fasteners for the last 5 years. You have provided me with the products that I have needed,with a price that is fair and a delivery on time. Thanks!

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 all round. The parcel arrived on my doorstep, in a regional Australian town, on the morning of the fifth day after placing my order.
