When fitting hinge screws I've noticed that, unless the pilot holes are perfectly aligned, horizontally/vertically/laterally and centered exactly on the holes in the hinge, the edge of the screw head is somehow always misaligned with the hinge hole by the time they're driven into the jamb.

In this case, the countersinking in the heads and hinge holes are a close size match, so even small discrepancies in position end up displaced to one side by up to a millimeter.

Driving it to resistance forces the head into the center position (I presume either by the metal bending or, possibly, the screw thread giving way slightly) but it still ends up tilted in its final position.

Is this normal when driving hinge screws, and can my technique be improved?

I'm also interested to know if it's the screw bending or the thread giving way that repositions the head of a misaligned screw. The screws are stainless steel and the jamb is beech headwood.
