Customer Reviews

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.
I've been a customer since 1983 and you have provided what I needed most times in a very timely manner at the right price. Over all I have been very satisfied with your company.
My order was handled extremely well. From placing my order online, through payment, communication of tracking, etc., everything was perfect. The package arrived in a timely manner, and all items were received in excellent condition.
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!
