Ordered on a Monday evening and arrived in New Zealand Friday afternoon. Very good prompt service and the compass was installed on the Saturday after calibration. Thanks Military Fasteners!

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!
