It is always a pleasure ordering from Military Fasteners. You can talk to a real, live, human being who is helpful and courteous thru the whole process. I received my order on time and as promised. Military Fasteners is my Go To place for all aviation supplies.

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.
