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.

Military Fasteners provided the supplies needed to repair my prop. They had the exact items I needed, at a good price. My order was delivered in reasonable time, complete with instructions. The end result was a quality repair to get me back flyin again. Thank you! Steve
