The screw shears if/when I don't stop in time. It hasn't happened
yet with the new Metabo but it would be nice to know if 53Nm is
capable of shearing an 8mm screw.


If it's so important why not contact the screw manufactures tech' dept.
and
ask them rather than ask a load of (mainly) DIY armatures ?!...

Try Timberloks. Great screws and new replacement for 12mm bolts.
