Customer Reviews

I have purchased most of my aviation needs from Military Fasteners for the last 5 years. You have provided me with the products that I have needed,with a price that is fair and a delivery on time. Thanks!
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.
To say I am satisfied with all purchases from Military Fasteners is a bit of an understatement. Selection, price, packaging, shipping exceeds expectations. You are my number one choice for my aircraft needs, thank you, Charles
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.
