Military Fasteners did an excellent job fulfilling my most recent order. This superior performance is typical for ACS. My order arrived in excellent condition within just 3 days of placing the order. Well done!

If your looking for a company that can provide you with technical help on a product that they sold you, this is not the place to buy anything. But they will tell you how sorry they are.

5.0

As always great service with fast shipping. That's why I always choose military fasteners first for my aircraft needs. Thanks.

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!
