Thanks for the quick service. Great price and quick service.

Ordered on a Monday evening and arrived in New Zealand Friday afternoon. Very good prompt service and the compass was installed on the Saturday after calibration. Thanks Military Fasteners!

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.
