You ship them right out to me via US mail in a padded envelope. This makes you my go-to company for all my parts needs. When I've asked questions on-line about an item they are answered thoroughly and usually the same day. Thanks 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.
