Whoever thought a 1.3mm allen key head machine screw with fine threads was a good idea for the set screw on my new bathroom towel rack was a good idea should be kicked in the balls.
Hole to the set screw is right up against the wall, also too deep for a ball head style key to allow a bit of angle. This way you only get a half turn max each time, but mostly about a quarter of a turn trying to get the key to seat in the screw head.

Others I have had all came with flat head set screws and were very simple to setup. This one is so over engineered its crazy.
