You all are Awesome! I am restoring a 1946 all aluminum camper and have come to you several times for materials needed. Every time I order, I get a quality product at a fair price in a timely manner. I couldn't ask for more.

Love the fact that you show your shipping rates prior to placing orders. Most of the time (95%) I choose USPS Priority, the least expensive

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!
