Drip groove itself are just bigger than a drip - so maybe 5 x 5mm. At least that's the sort of size I used to machine

It does doesn't it.
But on further examination it is just poor workmanship. It would appear that one of the holes through the body is not in the correct place, this misalignment is stopping the screw fitting correctly into its countersunk hole.
Disappointing in a tool designed for high accuracy.

Accuracy from a Parkside tool?????? Yeah right.
A Parkside tool designed for high accuracy does not exist.

I suppose they might be designed for high accuracy - whether they achieve it or not is an entirely different matter
They're designed to look like they're designed for high accuracy. But they're definitely not designed to archive high accuracy.

Parkside stuff is alright, you get what you pay for and with that in mind it is excellent value.
The calipers I have of theirs are absolutely fine, they do the job well. What I was meanng above about 'high accuracy' was more to do with perceptions, for a tool that is sold as a precission instrument, it could have been made a little more accurately than it has.
I wonder what went wrong in the manufacturing process to create a mistake like that, I wonder how many in that batch all have that exact mistake. Production machines run quickly, could be 50 or 100,000, all done before the brand name is stamped on.

The question is surely whether they give a damn, or whether the guy making the item (or at least drilling and tapping the parts) knows what the tool is being used for. Based on the "quality" of Chinese instruction manuals I'd say it is a combination of the two. Never mind the quality, feel the width?
You hit the nail on the head which trumps anything anyone can say about Parkside tools, its built cheap for the masses and generally works OK for it's intended purposes.
Regarding measuring tools such as Verniers, depth gauges, micrometers, etc
I have known high end ones to measure incorrectly because of how they were stored. i.e. on a shelf in a freezing shed or in a van on the dashboard.
They are usually calibrated in a room with the ambient temperature at 20C and they should be left in the room, (out of any cases), for 24hrs prior to calibrating.
We had an apprentice who was learning to be a metal turner working on lathes. Each time he was given a simple task it would always be undersized. Supervisor suspected he couldn't read the analogue dials on the lathe so 'taught' him over 2 days what each one meant and how to read them. Apprentice seemed to be able to read them so was told to do a sample job where the measurements on the lathe dials corresponded to the readings on his micrometer and vernier. He kept getting different readings each time he measured them, then it dawned on his supervisor he was measuring as soon as he stopped cutting so the steel was still warm. He was then cutting a bit more till the reading was correct on the hand tools but not with the machine gauges. Once he was told to cut to the machine gauges then wait a minute for the steel to cool, he was good.
