Customer Reviews

I sent in my online order then within a minute I realized I left off an item. I sent a message that requested an item be added to avoid a second shipping cost. I received a reply the next morning that the item I wanted had been added successfully and my order would be delivered as promised. Thanks to your staff for the flexibility and the help with my online order.
I've been using Military Fasteners for a long time and have always been more than satisfied with the service they provide. Craig F
You folks have always treated me well and supplied the product I needed, and the product I ordered and in a timely manner. I am working to build a Wag Aero Sport Trainer.
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.
