My order was shipped and received within two days. I always receive satisfactory service from Military Fasteners. Thanks.

5.0

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.
