Customer Reviews

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.
Yall keep me flying. The service is always prompt and accurate. Thanks so much.
Amelia does a great job for Highpoint.
Everything was professional. Never talked to anyone, just online order.
