I am very happy with all the orders I get from Military Fasteners, very good and fast service, Very friendly staff. Thank you.
10/10 love working with Amanda! She’s always eager to get on the phone with customers and ready to get their orders out the door.
Very fast response to RFQ (less than 1 day) very competitive pricing and low MOQ requirements
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!
