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!

Received the ELT Battery on time and at a price that I expected. I use Military Fasteners for all my aviation part and accessories needs.

I sent in my online order then within a minute I realized I left off an item. I sent a message that requested an item be added to avoid a second shipping cost. I received a reply the next morning that the item I wanted had been added successfully and my order would be delivered as promised. Thanks to your staff for the flexibility and the help with my online order.
