I experienced the exact same issue, my 12mm 12 point socket did not fit tight on the OEM bolts. I almost stripped one while removing them as well, but I was able to remove all of them in the end. All of the DIY's I've ever seen for the S65 rod bearings list the 12mm 12 point socket. I chalked up my experience to a low quality socket, but after looking up the double hex just now I wonder if you aren't on to something there. Just be careful and you should be fine, many other people have completed the job with the socket you have.
2025 Edit: I have since learned the rod bolts were manufactured with the German "DIN" standard dimensions and contours required by that standard (similar to SAE and ASME standards from the U.S.). Because of this, sockets manufactured to DIN standards or manufactured specifically for DIN standard fasteners fit better on these BMW rod bolts and all of the other screws/bolts on the car. German branded tools present with a better/tighter fit such as Hazet, Stahlwille and Wera in my more recent experience.
