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.

Military Fasteners is first on my list for the hard to find items so often associated with Government Projects. Brittany and Michael have always been quick to respond and nothing but professional in every way. I look forward to a continued relationship with Military Fasteners.
