Customer Reviews

I order parts about once a week for the restoration of my Grumman AA-1A. Service and prompt delivery are always above expectation. I don't know what I would do without Military Fasteners and that's no joke! Thanks for your great work!
I worked with Isaac Beltran and he did a great job and rare to find.....someone with attention to detail.
Staff very supportive and informative. Order was shipped extremely promptly and correctly. GREAT customer service!
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!
