Customer Reviews

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!

Military Fasteners was recently added to our list of approved vendors and so far it has been an absolute pleasure working with them. The speed, communication, and coordination with our orders so far have been absolutely above and beyond. Sarah is an absolute all star and made the ordering process quick and seamless. 10/10 Would recommend to anyone looking for products!
