I called in a hot order that was needed next day. It was already mid afternoon and i had already skipped the deadline for shipments that day. I spoke with Trisha, and she went out of her way to place my order and get it pulled and shipped same day. Thank you Trisha, you are the best.

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!
