Paige is the best :)

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.

I ordered a replacement aircraft battery from you and the service was excellent. The turnaround time was very good and the product was exactly what I ordered. I have used Military Fasteners in the past and will continue to do so. I am a satisfied customer.
