I was impressed with the speedy delivery of my order and also with the order itself.

I have been buying from Military Fasteners for the last 6 years... You are always the best...very prompt!! Thank you!!

4.0

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!

The products sent allowed the repair to be completed in a timely manner. Thank you for Military Fasteners being there and having parts available to allow our vintage aircraft to continue flight.
