Google says the head of the flat bit is 6.4mm so with the screw holding function of it then it probably will do it but there might be a bit of play sideways.(assuming there’s room for the end to fit if fixing back detector heads or sounders)
I’ve just tried a few different m4s from the random bit box and there’s some variance in the slot width between manufacturers.
Using a standard 1/4 flat screwdriver bit, either a 7mm or 8mm flat bit would hold the m4 securely enough to hold it upside down without the screw falling off.
