Ramona was awesome when it came to helping me source some hard to get and not commonly used fasteners for a special project we are working on. Thanks Ramona!

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!
