Explain this line to me, please?
I am reading a document about a light source for medical purposes and I don’t understand the expression in brackets. I am not a native English speaker. Please, explain this expression to me, thanks:
“Disassembly of rotating coupling:

- Pull the front cover forward and remove the sliding disk.

This is the description of the two metric screws holding the cover on.

There are quantity two fasteners that are M3x5mm (M3 is a 3mm standard pitch thread, 5mm is the length of the fastener). DIN 915 refers to the type of fastener which is a set screw. This is what I would expect to be found in European manufactured equipment.
