Military Fasteners is my main go to catalog to find the majority of parts I need for the aircraft that we work on, and the more parts they have available more I will keep coming back. Their customer service is superb and theyre shipping is excellent. Ive used Military Fasteners for many years and will continue to use them since I know I can find a majority of the parts that I need and the price is very reasonable. I would like to say thank you to all the supporting staff for help me locate items that I need and information on products they have.
