Phillips and Pozidriv cross-head screws – explained in simple terms
the conical Phillips form generates an ejection force that pushes the screwdriver out of the screw. With Pozidriv, the parallel form prevents this force. Advantage of Phillips - Disadvantage of Pozidriv [...] inserting the tip of the screwdriver with the power-operated screwdrivers. In addition, an axial force is generated during tightening which pushes the screwdriver out of the screw. Originally, this effect [...] American Screw Company patented a cross-head screw with parallel flanks which prevents the ejection force during tightening or loosening. The name Pozidriv is the abbreviation or acronym for "positive drive"
