Props to my saleslady (whose name I have sadly forgotten) for her can do attitude. Fast and efficient yet friendly and thorough. The items arrived nicely padded with brown paper. Im so happy youve stopped using those hard-to-dispose-of styrofoam peanuts. Fast to ship reasonable prices. Just excellent all around!

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.

In the long time that I have used Military Fasteners to provide materials and equipment in the building of two airplanes, I have yet to have a bad experience. Keep up the good work!
