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.

Great product at a good price, fast delivery. Easy install, fired up perfectly right out of the box.

4.0

Military Fasteners is first on my list for the hard to find items so often associated with Government Projects. Brittany and Michael have always been quick to respond and nothing but professional in every way. I look forward to a continued relationship with Military Fasteners.

Military Fasteners is one of my top hardware suppliers. If you can't find a mil-spec part, they will find it for you. Shipping is always fast and reliable. Kristen is phenomenal to work with. Highly recommend.
