I can always count on Military Fasteners to give me the best selection of aircraft parts and supplies. Also always get fast shipping, and appreciate the USPS option that is much less expensive than the overnight shippers for us located in Southern California. Thank you for making it easier to keep our general aviation and experimental aircraft flying!

Omari N.

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.
