Customer Reviews

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.
Military Fasteners never fails to have exactly what I am looking for and at a great price as well. Their quick turnaround allows me to have what I order in hand before my deadlines. Would definitely recommend them every time.
Ive been buying aircraft parts and supplies from Military Fasteners for 3 years as Ive built four different homebuilt aircraft. I have ALWAYS been perfectly satisfied with all facets of the process. Parts are almost always shipped the same day as I order them, even if I order in the afternoon. Im usually always able to find what i need on the website, and if not, I can call and be helped by someone who knows what he or she is doing. Your people make me feel like they really care about me. Prices are fair. I wish I could run my company as well as you run yours!
As a race car owner and builder I find your pricing and selection of AN hardware and composite materials more than meet my needs and expectations.
