No, they use a specially designed driver that sets the "depth" of the
screw. When that depth is reached, the "clutch" disengages - not a
"cam-out" function at all. Otherwize you could just use a drill with a
$0.99 philips bit to hang drywall.

You can't be serious. A device that actually sets the depth the screw can
penetrate, then contacts the drywall, and automatically disengage the bit?

Preposterous.
