Customer Reviews

Everything arrived quickly and correctly. I'm a longtime customer and find your service to be always top of the line.
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.
The customer service from Trisha Hawkins at Military Fasteners was exceptional.
Yall keep me flying. The service is always prompt and accurate. Thanks so much.
