Ramona was awesome when it came to helping me source some hard to get and not commonly used fasteners for a special project we are working on. Thanks Ramona!

This is just a note to say how much I appreciate Military Fasteners. Your prices are fair, your shipping is fast and the costs are reasonable. The paper and online catalogs have a huge assortment of products. I also like the fact that there is no minimum order.

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.
