Customer Reviews

I could find those 2 great different products for my Garmin at the same place. Thank you very much, very helpful, very easy to order and fast shipping.
I have built an airplane with parts from Military Fasteners. In the last years I have only had one issue involving warranty problems and that was resolved by the factory. Good service and quality parts/availability are very good at Military Fasteners.
Thank you for very efficient and quality service. The product was exactly as advertised, price was good, and the shipping was very fast. I am very happy with my first experience with your company. I will for sure be continuing my business with you. Keep up the great work.
I recently had the pleasure of working with Dan Hunter and I must say that my experience was nothing short of exceptional. Dan is the epitome of professionalism and knowledge in the Aerospace industry. From the moment I engaged with Dan, I was impressed by his deep understanding of the products/services he was selling. His expertise was evident as he patiently and thoroughly answered all of my questions, providing me with valuable insights that helped me make informed decisions. What sets Dan apart is his ability to build trust and establish rapport with customers effortlessly. I never felt pressured or rushed into making a purchase; instead, I felt supported and guided in finding the right solution for my needs. Ask for Dan if you are looking for a salesperson who goes above and beyond to deliver an exceptional customer experience.
