I just ordered four very tiny items for a couple of bucks and you treated me like I ordered much much more. The order got to me in just a few days and all I can say is your company is at the top of my list. Thank you very much. Stan

My experience in doing business with Military Fasteners through Trisha Hawkins is nothing short of GREAT! She is knowledgeable, attentive to detail and very helpful. This makes my purchase a lot easier and faster lead time. She is an asset to Military Fasteners.
