I have been using Military Fasteners and have always had great service. Just this week I realized late in the day that we needed another part and I was able to add it to the order I had placed that morning. Being a small FBO on a shoestring budget that saved shipping cost and potential delays. Thanks Military Fasteners.

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.
