Great service when calling in orders, very knowledgeable staff. The web site is also very user friendly for ordering and shipping is quick. I give it a 5 star rating.

Always very helpful Employees. Stock seems to be getting better as well. No problems ever.

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.
