Customer Reviews

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.
I love your website. Can hardly believe how fast & accurate the orders come. Am building a kit plane, need a lot of small hardware and electrical the past few months. There has not been a mistake in the last dozen orders.
Great service, I run a small GA workshop and I can count on Military Fasteners even though I'm in Australia, its quicker than getting it in Australia most of the time. The web site is great and simple to find the parts needed.
Ive been purchasing aircraft parts and hardware from Military Fasteners for over 4 years. That alone should speak volumes. Ive always received excellent customer service and the product quality is unrivaled. When I think of aircraft parts and accessories, Im thinking Military Fasteners. Keep up the excellent work folks! Regards, Ed
