I enjoy ordering my components from military fasteners because your people that take my order have always got my order right. They are also very polite and professional. Thank You

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.

Alternator was in stock, shipped same day, arrived quickly (even though I chose standard shipping during the height of the Christmas rush), packed well and at a good price. Well done, Military Fasteners, well done!
