I have experienced 5-star customer service from Isaac Beltran at Military Fasteners. He is a true professional who goes out on a limb to help out his customers. I always check with Isaac when I need help with finding those hard to find items". Thank you again Isaac for your support!"

5.0

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!
