I have dealt with Military Fasteners a few times and they have always been extremely helpful and knowledgeable. Ramona has always been wonderful to work with and goes out of her way to help you find what you need. Definitely recommended!

I've probably had over 50 separate orders over the past. Every one was delivered promptly and was correct.

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.
