I placed an order with Lindsey at Military Fasteners late afternoon, 3:15 to be exact and she was nice enough to expedite my order and made sure to get it shipped that day. Great company with great people.

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.
