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.

As normal with Military Fasteners for many years, no issues. I order the parts needed and they send them. Just fair prices and good service.

I just ordered four very tiny items for a couple of bucks and you treated me like I ordered much much more. The order got to me in just a few days and all I can say is your company is at the top of my list. Thank you very much. Stan
