In the long time that I have used Military Fasteners to provide materials and equipment in the building of two airplanes, I have yet to have a bad experience. Keep up the good work!

5.0

I've been ordering from Military Fasteners for quite a few years now and have always been completely satisfied with their service. Being not to swift with my laptop, I place my orders by phone and always receive quick response.

Trish is very responsive and helpful

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.
