Customer Reviews

We worked with Ramona at Military Fasteners for a few items that we needed right away to complete a job. Ramona processed our order quickly and efficiently and made the experience stress free when it could have been quite challenging. The items came with all the correct documentation too which was also very important to us.
In dealing with Military Fasteners for 3 plus years, I can honestly say Ive never had a bad experience with the company. Please keep up the great work and youll keep me coming back for as long as I am flying.
Very good service, as usual. Order was complete and correct. It is easy to order on your website and the deliveries are always in the specified time.
Products are military grade MIL-SPEC as advertised. I was able to locate #10 locking counter-sunk nutplates when ALL other locations, including Aircraft-Spruce, could not supply.
