Fastener design
(OP)
Has anyone come across the idea of making countersunk screw heads slightly out-of-square so that when a required torque is reached the screw does not 'slam into the hole' and cause thread to strip?
The application is joining thin metal strips together using a thread forming screw, hence not much thread in the sheet being screwed into.

Just set the pressure correctly(torque) and you should be good to go.
