Devin from shipping dept. was a fantastic help! Great support and service.

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.

I just want to say that I am really liking what is going on with Military Fasteners. The prices, the availability of items, the fast shipping. I really like the ease of ordering online. I have been to so many websites that are confusing to say the least, but yours is easy easy to use, clear and simple. I love being able to look up all my past orders and print out the invoices if need be. I am just thoroughly impressed with everything about Military Fasteners. Keep it up and you will always be on my bookmarks bar in the number one position!

Another good experience with Military Fasteners, and our Sales Rep, Dan Hunter. We needed hardware for an older aircraft model, and Dan's expertise was exceptional. He quickly identified fasteners, even for parts with unclear descriptions, and provided invaluable technical assistance. The supporting data was spot-on, verified by our technicians. Despite finding slightly lower prices elsewhere, the unmatched service and expertise from Military Fasteners, particularly Dan, make them our preferred choice. Our order was delivered ahead of schedule. Highly recommend MilFast for top-notch service and technical support!
