As always great service with fast shipping. That's why I always choose military fasteners first for my aircraft needs. Thanks.

4.0

Just received my order and I would like to congratulate you on such fast and efficient service. You are excellent at what you do and I always recommend you to others. Great company, it's a pleasure dealing with you, well done once again!

5.0

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!
