d) The manual says this should be a M8 screw. This was clearly wrong,
the screw is 5/16-18.

You know that 5/16 is *very* close to 8mm?

The critical point is that this set screw would not go into * the hole
it came out of in the first place*. It was not particularly difficult
to unscrew either.

It was a perfect fit into a 5/16-18 screw gauge.

I can find no evidence that M8 with 1.5 mm pitch exists - all the
references I have seen mention only 1mm and 1.25 mm pitch in this
size. What are the odds that a set screw of this nature would be of so
uncommon configuration?
