G'day all. Trying to determine the type of caliper mounting bolt on my 2018 Street Glide. It's not torx head, possibly double hex? Any info would be appreciated.

its a fancy bolt that takes a standard 12 point socket, I only took off the wifes triglide front wheel last week and cant remember the size, I even asked the dealer about it and he said that it was a normal size socket

yep...12 point bolts.  best to buy the right 12 point socket as they fit like a glove!

Cheers for that mate.

Thanks for the info.
