I had the opposite problem when installing my 930s. I have socket head bolts and was looking for allen head. I had the same issue finding the correct thread pitch. Anyway, I gave up and used the hex head bolt.
My solution to the access was a 19mm offset box end wrench. I ended up cutting off the opposite end of the wrench in order to clear the oil lines on the right side.
I also tried the cut down socket but the offset box end wrench worked much better for me.
