Great product at a good price, fast delivery. Easy install, fired up perfectly right out of the box.

4.0

Enjoyed the order experience. Easy to find. Easy to order.

5.0

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!

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
