Phillips Head Screwdriver
Also known as
Phillips, Cross-Head Screwdriver, PH2 Screwdriver, Cross-Point Screwdriver
Used for
Driving Phillips-head screws on audio, lighting, and video equipment — rack screws, panel screws, and equipment covers are almost always Phillips. A PH2 handles the majority; a set from PH0 to PH3 covers edge cases.
Trade note
Named after Henry F. Phillips, who popularized the cross-head drive in the 1930s. The self-centering design was ideal for early power screwdrivers in automotive manufacturing. "Cam-out" — the tendency of a Phillips driver to slip out under high torque — is a design feature, not a flaw: it prevents overtightening on assembly lines.
