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!

Everything I ordered was delivered quickly, packaged well. In fact, all of my prior orders as well.

5.0

I have built an airplane with parts from Military Fasteners. In the last years I have only had one issue involving warranty problems and that was resolved by the factory. Good service and quality parts/availability are very good at Military Fasteners.
