I was very pleased with the processing of my order from Military Fasteners. Placed my order very late on Thursday. Confirmation was immediate and received a tracking number the next day. It was delivered on the Monday. Excellent service from Military Fasteners

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.

I love your website. Can hardly believe how fast & accurate the orders come. Am building a kit plane, need a lot of small hardware and electrical the past few months. There has not been a mistake in the last dozen orders.
