Have to tell you that you have the best in Brittany Cornish. She is always the most help in getting our ordered placed as soon as we send it in and always on time delivery. She is very responsive with any and all issues if any which we never have any dealing with her. She always goes above and beyond to follow up even after we received our order. We only wish all of our Vendors that we deal with on a daily basis were as wonderful as she is. Her personality is bar none.

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!
