Customer Reviews

I was working with Kasey and she was very helpful. I received our fasteners very fast.
Military Fasteners was recently added to our list of approved vendors and so far it has been an absolute pleasure working with them. The speed, communication, and coordination with our orders so far have been absolutely above and beyond. Sarah is an absolute all star and made the ordering process quick and seamless. 10/10 Would recommend to anyone looking for products!
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.
Excellent variety, quality, and service. And, small orders are no problem. Military Fasteners is a tinker's delight and a great resource. I also appreciate their using the USPS. So many companies ship UPS only and to Alaska the UPS price is ridiculous. Thank you.
