excellent customer service!

Military Fasteners always delivered on what I purchased. And what I returned Military Fasteners is prompt on returning it as crediting my account. I only order for myself, so I'm quite satisfied the way Military Fasteners takes care of me only as a occasional customer. Thank you Military Fasteners Personnel.

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.
