oboe,
they're M4 screws, which fit into a steel insert moulded into the plastic.
It's possible to drill and re-tap the threads, but tricky, so you might be best to abandon the original fixing positions and make new ones 60 degrees round.
I'd recommend using stainless M4 set screws with a hex head, not those bloomin' crosspoint/phillips head screws.
