I have dealt with Military Fasteners a few times and they have always been extremely helpful and knowledgeable. Ramona has always been wonderful to work with and goes out of her way to help you find what you need. Definitely recommended!

You folks have always treated me well and supplied the product I needed, and the product I ordered and in a timely manner. I am working to build a Wag Aero Sport Trainer.

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!
