Customer Reviews

Happy to find the items needed and the service was very quickly completed.
Ramona was awesome when it came to helping me source some hard to get and not commonly used fasteners for a special project we are working on. Thanks Ramona!
I have been dealing with you folks for years as a corporation customer and personally. You are the industry standard on quality of product and service.
I order parts about once a week for the restoration of my Grumman AA-1A. Service and prompt delivery are always above expectation. I don't know what I would do without Military Fasteners and that's no joke! Thanks for your great work!
