I've been buying from Military Fasteners for about 2 years. In that time, I don't ever recall having a bad experience. Please keep up the great work and continue offering the fair prices, fast shipping and excellent customer service.

4.0

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.
