After an extensive look for parts, Ramona Real of Military Fasteners was the one that could help in finding what I needed and provide the necessary paperwork to go with it. Shipping on time and packing perfect. Good people to work with and highly recommended A+++++

Great Delivery time, thanks for your fast response Trisha H

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!
