The holes to mount the derailleur hanger area smaller than the receiving holes, which are also threaded. I’ve been doing this for some time but haven’t come across this yet. Thanks for your help.

Screw hanger on back of dropout first, then attach derailleur from outside.
Step 1 – remove derailleur from the hanger (not strictly necessary but helpful).
Step 2- mount the hanger. The hanger goes in between the frame and the hub..
Step 3- the screws go from the outside (frame side) through to the hanger. Tighten
Step 4 – Reattached derailleur.
Are you…. Are you working in a bike shop? 😅
Been wrenching on bikes for years and you got the hanger on the wrong side of the dropout mate. The hanger sits behind the frame, against the inside face of the dropout, then the derailleur bolts onto it from the outside. Looks like you were trying to sandwich it the other way around and that’s why the holes aren’t lining up properly. The threads in the frame are just there to receive the bolts that pass through the hanger. Probably happened to most of us once, just one of those brain fade moments where you stare at it for an hour and can’t see the obvious answer. Once you’ve got it sorted the rest will click and you’ll be giving yourself a shake of the head for the next week.
