Use sacrificial screws to thread the tower tube wall in advance and then flatten the point of the actual screws before insertion. Keep in mind that stainless steel hardware is softer than normal and is prone to breaking. As an alternative you could drill and tap and use three tiny fine thread machine screws with blunt tips.
