I am replacing some old wall lights with some new Där fittings. I was
somewhat surprised to see that the wallplugs and screws supplied were of
different lengths. The wallplugs were 25mm x 5mm, and the screws 35mm x
3.5mm. The diameters match well, but why would you use a 35mm screw with
a 25mm wallplug?

You recess the plug into the wall so that it is not putting any strain on
the plaster.


Who else does that?

I do. Sand/cement skimmed plastered wall. Two reasons, one to
avoid risk of plaster cracking, two I am securing item to the
brick, not the plaster. I often discard supplied screws and plugs
and fit longer ones.

Sand & cement ? Sounds like render again

The skim is plaster, though I can't see it makes any difference in
terms of sinking the plug below the surface which was the
original question.Sink it to avoid cracking the
surface.
