In this day and age, it is rare to be impressed by customer service however, Military Fasteners has far exceeded my expectations. They went above and beyond to help ensure an important package delivery on time, and they made a little boys Christmas sweeter in the process. Thank you to the team there for your wonderful help. I will certainly come back to shop again and again. They always say, fly people are the best people.

4.0

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!
