Customer Reviews

Hard to find bolts are never hard to find with Military Fasteners!
I've been a customer since 1983 and you have provided what I needed most times in a very timely manner at the right price. Over all I have been very satisfied with your company.
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.
Abby is awesome and very helpful! I can always hear her smile through the phone!
