Everything about this order was textbook perfect. As always,when I order something from Military Fasteners I get what I ordered when it arrives on time. No surprises or disappointments. Good job!

4.0

Thanks for being there for us small plane owners. It has never been cheap to own a plane but as our planes age it is getting harder and harder to find parts for upkeep. Good fast service also.

5.0

I had ordered the wrong spark plugs and didn't notice until the day I was changing them. Spoke to a very helpful customer service person who walked me through the RMA process. New plugs arrived in 2 days and the refund was applied as soon as AS received the returned product. I've been using AS for over 25 years and have always been impressed with the service.

4.5

Military Fasteners always seems to get the order correct and delivered when expected. I this day and age, this is high praise.
