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!

Fast, efficient, knowledgable, good all round people and I will be doing more business with them. I have an older plane and it is needing some refinements. Thanks for your service!
