My order was handled extremely well. From placing my order online, through payment, communication of tracking, etc., everything was perfect. The package arrived in a timely manner, and all items were received in excellent condition.

4.0

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!
