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.

Brittany was attentive to our needs. We had to source some other products you didn't have elsewhere. We would have preferred to place an order a one place. Will come back and order another time.

This is just a note to say how much I appreciate Military Fasteners. Your prices are fair, your shipping is fast and the costs are reasonable. The paper and online catalogs have a huge assortment of products. I also like the fact that there is no minimum order.

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!
