I can say that Military Fasteners was able to deliver the part to me very quickly. I live in a very remote area in the Tennessee mountains and typically have to wait up to two weeks to receive deliveries. Sometimes, the delivery guys cannot find my house at all, and they have to leave my packages at the local general store. But with Military Fasteners, my packages always find my front door step and in great condition. This package arrived nearly a week earlier than expected, and that was over the New Years holiday! Great work, Military Fasteners, on your delivery service. Thanks!

Military Fasteners always delivered on what I purchased. And what I returned Military Fasteners is prompt on returning it as crediting my account. I only order for myself, so I'm quite satisfied the way Military Fasteners takes care of me only as a occasional customer. Thank you Military Fasteners Personnel.

As always, orders are shipped promptly and received when expected. Rarely can you find products at lower cost than at Military Fasteners. The web site is easy to use. My favorite place to order from. When looking for aviation products, I always go to Military Fasteners first.
