Couldn't be better: shipped fast, price was fair, product exactly as expected. Will always order from Military Fasteners going forward.

5.0

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!

All of my orders have originated thru your online system and have arrived on time as advertised. Your system performs great. I can decide while ordering how I want it shipped and what cost. All things said, I find your system very easy to order thru.
