Upon mounting the heated bed pcb to the bed plate, I’ve noticed that the bolts used here are not flush with the pcb’s surface, but are standing above the surface for guesstimated 0.5 mm.
That’s the bolt which can be seen here:

and here

I don’t want to tighten these bolts with too much force, since that would warp the pcb.
Hence the question if it would be advisable to enlargen the screw holes.
Presumably most prints would be inside the square surrounded by these four bolts, but when affixing a glass plate to the heated bed pcb it wouldn’t touch the pcb’s surface. Instead there would be a .5mm gap between pcb and glass plate.
When printing something larger than the square area between the bolt heads, the extruder’s nozzle might contact these bolts … I fear that that would be less than optimal.
Again, thanks for any enlightening hints.
