Enviro Weather pcb holes -> 2.5mm?

H All,

About : Enviro Weather (Pico W Aboard) - Board Only

The holes in the pcb corners are (I believe 2.0mm). My regular 2.5mm nylon screws don’t fit. Is the pcb design leaving spare board material around the holes to drill them to 2.5mm ? I.e. no little wire routes insanely close to the holes?
