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.

I need more stuff and plan on placing another order soon! Thank you!

Keep on keepin' on! Living in Nova Scotia puts me in somewhat of an aviation backwater where getting aviation hardware can be a bit of a nightmare. Military Fasteners resolves most of the angst and dealing with the friendly and helpful staff I find there resolves the rest.
