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.

All my orders have been easy to make and quickly shipped. I was a business owner for over 40 years and only wish my businesses could have been as efficient. My first choice in ordering aircraft parts..

Hard to find bolts are never hard to find with Military Fasteners!

The competition cancelled my order saying it could not be shipped. Very impressed with the service. Military Fasteners will be the first people I call in future:)
