When fitting hinge screws I've noticed that, unless the pilot holes are centered exactly on the holes in the hinge and at a precise (within 2-3 degrees) horizontal/lateral right angle to the hinge plate, the edge of the screw head is always misaligned with the hinge hole by the time the two come in contact.
In this case, the countersinks in the screw heads and hinge holes are a close size match, so even small discrepancies in position/angle end up with the head 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.
In DIY videos concerning hinge installation, instructors, DIYers and professionals often drill pilot holes, almost casually, at funny angles, and drive the screws straight in without thought to position. I'm thinking they must have the same problems but aren't bothered by it or using a method unknown to me.
Is this just me being needlessly perfectionistic? If not, can my technique be improved?
I'm also interested to know if it's usually the (stainless steel) screw bending or the thread (in hardwood) giving way that repositions the head of a misaligned screw when it's driven to resistance.
