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.

Love the fact that you show your shipping rates prior to placing orders. Most of the time (95%) I choose USPS Priority, the least expensive
