As always, Military Fasteners demonstrated they value all their customers, in their handling a back order product..Thank you!

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!

As usual Military Fasteners did a great job getting the items I ordered to me here in Arizona. My last order had one item on Back Order but was sent in a timely manner direct from the manufacturer. Great Company, great service.
