I was very pleased with the processing of my order from Military Fasteners. Placed my order very late on Thursday. Confirmation was immediate and received a tracking number the next day. It was delivered on the Monday. Excellent service from Military Fasteners

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!

I was looking for hard to find parts for a safety critical application. The first couple of places I tried had the part on their web page but when I tried to order it they said, sorry, they did not actually have the parts. I called Military Fasteners. Talked to an employee without delay. She looked up the part number, told me who manufactured them (important), where the company is located (very important) and shipped the parts immediately from their own inventory. Super nice, helpful, efficient and knowledgeable. They get it.

Military Fasteners is my 'go to' aircraft supply company. Every purchase has been a pleasure. Great products and shipping is good. Shipping cost is always a concern but I know you have little to due with that. Thank you Military Fasteners.
