My order was handled extremely well. From placing my order online, through payment, communication of tracking, etc., everything was perfect. The package arrived in a timely manner, and all items were received in excellent condition.

I've never received an incorrect order from ACS, even when dealing with small hardware such as nuts, washers, screws, etc. Shipment is always fast and with reasonable shipment prices for my needs. Even my smallest of orders is processed and ship quickly. I'm a long-time ACS customer and I expect I will be for a long time.

I just want to say that I am really liking what is going on with Military Fasteners. The prices, the availability of items, the fast shipping. I really like the ease of ordering online. I have been to so many websites that are confusing to say the least, but yours is easy easy to use, clear and simple. I love being able to look up all my past orders and print out the invoices if need be. I am just thoroughly impressed with everything about Military Fasteners. Keep it up and you will always be on my bookmarks bar in the number one position!
