Cheers for the replies guys. There seemed to be a metal sleeve around the stud that was sitting inside the mount. (Have now looked at Servicebox n it's described as a spacer 1814.29). It was loose-ish but didn't seem to want to slide down past the threads. Looking as the schematic it looks like it would cover the hex part of the stud n only slide upwards off it. It's possible I didn't try hard enough to pull it out!
The stud went back in with a good dose of thread lock so hopefully it won't be a problem again.
