Phillips Screws: Designed to StripWhy the cross-shaped head rejects your tool on purpose.

Why it looks like that

Anyone who has used a power drill knows the frustration of the bit slipping out of the screw head and shredding the metal. This phenomenon, known as "cam-out," isn't a defect—it is the specific engineering reason the Phillips screw exists. Designed for the assembly lines of the 1930s, the tapered cross shape was engineered to physically push the driver out of the slot once a certain tightness was reached. This intentional slippage prevented powerful industrial machines from snapping the screw heads or crushing the delicate aluminum parts of early cars and aircraft.
