Hello, I am an Estimator for CAMCO Mfg. Inc. We work with many Prime companies that require Military Fasteners. Kristen Belmont is always the first to respond and gives me great service! She guides me with her knowledge and treats me w/much respect (even when I don't know what I'm talking about) Out of all the outside sources I have to work with, I enjoy working with her best!

My company works directly with Military Fasteners, and we have had nothing but positive experiences. Trisha Hawkins, in particular, has been our primary contact. She always responds quickly and works to make sure the order is correct and shipped on time. Military Fasteners is a trusted vendor of ours and we look forward to working with them again in the future!

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.
