Happy to find the items needed and the service was very quickly completed.

Experience has been great the whole time, simple and easy website to use, no complaints. Even our rep, Trisha Hawkins, has been nothing but helpful to us. 5/5

I am unable to add any suggestions. Military Fasteners is an on time provider. I have never understood why the orders from you company are shipped and arrive in time given to me. Other companies say same day ship or the following day and it takes much much longer for the product to arrive. All I say, Good Job

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!
