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.

Tanks for the fantastic service. I ordered over the new year period and was amazed my shipment arrived so fast, all the way to New Zealand. Less than a week and that included clearing Customs. Awesome!!

5.0

As always, orders are shipped promptly and received when expected. Rarely can you find products at lower cost than at Military Fasteners. The web site is easy to use. My favorite place to order from. When looking for aviation products, I always go to Military Fasteners first.

I routinely use Military Fasteners and have them on our Approved Vendor List. They already understand traceability requirements and their website always seems up to date and accurate. Same day shipping is a big deal for us as well."
