Customer Reviews

Any enquiry I have made has been dealt with the utmost professionalism and trusted advice.
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.
My orders have been delivered on time or earlier all packaged well and in good shape. Thank you Military Fasteners.
Fast service and fast shipping.
