Your staff is courteous and well informed about your product line. Your inventory is excellent and competitively priced. The shipment always arrives as advertized and the boxes are well packed. I will continue to order my aircraft supplies from military fasteners

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 am always impressed that you can process and ship and order only a few hours after you get it. Keep up the good work.
