Order arrived promptly and well packed. Was exactly as described and worked flawlessly. Happy Happy!

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!

Ramona was awesome when it came to helping me source some hard to get and not commonly used fasteners for a special project we are working on. Thanks Ramona!
