Military Fasteners is an exceptional company in terms of how they run their business. Very prompt and responsive to questions, concerns, quotes, and all other forms of inquiry. Brittany Cornish supports many of the business transactions we perform with Military Fasteners and has made working with them an absolute pleasure. I would highly recommend them to anyone seeking mil-spec hardware.

5.0

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.
