Default Screw/wallplug size

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?


A wall plug works by the screw expanding it so it grips the brick or
whatever. The hole in the wall must be longer than the screw anyway.
