Customer Reviews

I found your company via Google and I am glad I did. It was very easy to order the item that I needed. I will definitely be back. Thank you!
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!
I could find those 2 great different products for my Garmin at the same place. Thank you very much, very helpful, very easy to order and fast shipping.
