We worked with Ramona at Military Fasteners for a few items that we needed right away to complete a job. Ramona processed our order quickly and efficiently and made the experience stress free when it could have been quite challenging. The items came with all the correct documentation too which was also very important to us.

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!
