The ordering process was very smooth and your site is user friendly and my part was delivered promptly.

5.0

Order was filled perfectly. I know I can rely on Military Fasteners.

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!

As normal with Military Fasteners for many years, no issues. I order the parts needed and they send them. Just fair prices and good service.
