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.

I've been an Military Fasteners customer years. It has always been a pleasure to order from you. There has rarely been an issue with an order but when there was you fixed it promptly.

Ashili Hansen was instrumental in sorting out a log-in issue I had. Ashili also assisted me in identifying several unique aircraft hardware items. All were in stock, shipped immediately, and at a competitive price!

I can always count on Military Fasteners to give me the best selection of aircraft parts and supplies. Also always get fast shipping, and appreciate the USPS option that is much less expensive than the overnight shippers for us located in Southern California. Thank you for making it easier to keep our general aviation and experimental aircraft flying!
