Customer Reviews

Very pleased with my order. Everything in my order was exactly what I had ordered and the price was fair. Delivered within two days of placing order.
Discovered on Wednesday evening I needed a new tire / tube. I had it in my hands Friday in time for a weekend install. Great 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!
Wonderful experience here, Dania was amazing!
