What it concludes

Phillips screws were originally designed to cam out to prevent over-torquing in aircraft manufacturing.
JIS screwdrivers fit both JIS and Phillips screws better and prevent cam-out compared to standard Phillips screwdrivers.
JIS screw heads can be identified by a small dimple mark, though not all have it.
Pozidriv screws offer more grip and less cam-out than Phillips, and are common in Europe and IKEA furniture.
Using JIS bits for Phillips-type screws improves grip and reduces slip without requiring magnetism.
