Ramona R. is very prompt and professional processing my urgent request! i am very satisfied with the quick turn around. Thank you!

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.

I have been using Military Fasteners and have always had great service. Just this week I realized late in the day that we needed another part and I was able to add it to the order I had placed that morning. Being a small FBO on a shoestring budget that saved shipping cost and potential delays. Thanks Military Fasteners.
