In the long time that I have used Military Fasteners to provide materials and equipment in the building of two airplanes, I have yet to have a bad experience. Keep up the good work!

5.0

I always receive my shipments from Military Fasteners quickly without having to follow up and track down shipments. West Coast shipments arrive usually the next day via UPS ground, making it an effective choice. Thank you for excellent service.

4.0

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.
