Best Support from you.

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 service, I run a small GA workshop and I can count on Military Fasteners even though I'm in Australia, its quicker than getting it in Australia most of the time. The web site is great and simple to find the parts needed.
