Excellent service, parts arrived at my home in UK exactly when you said they would even when you did not have parts in stock when ordered, very prompt reply to my queries before ordering, faster delivery than I would have got from UK.

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!

Another good experience with Military Fasteners, and our Sales Rep, Dan Hunter. We needed hardware for an older aircraft model, and Dan's expertise was exceptional. He quickly identified fasteners, even for parts with unclear descriptions, and provided invaluable technical assistance. The supporting data was spot-on, verified by our technicians. Despite finding slightly lower prices elsewhere, the unmatched service and expertise from Military Fasteners, particularly Dan, make them our preferred choice. Our order was delivered ahead of schedule. Highly recommend MilFast for top-notch service and technical support!
