480-4-PZDX Apex Pozidriv ® Insert Bit Description

The shallow cross indention in the screw head identifies a Pozidriv ® fastener. The Pozidriv ® bit and recess design provides better contact than a standard Phillips ® for more torque. The Pozidriv, sometimes misspelled Pozidrive, screw drive is an improved version of the Phillips ® screw drive. The Pozidriv ® bits' advantage over Phillips ® drives is its decreased likelihood to cam out, which allows greater torque to be applied. Apex Pozidriv ® bits are very similar to, and essentially compatible with, the Supadriv screw drive.

Phillips ® drivers have an intentional angle on the flanks and rounded corners so they will cam out of the slot before a power tool will twist off the screw head. The Pozidriv ® screws and drivers have straight sided flanks. The Pozidriv ® screwdriver and screws are also visually distinguishable from Phillips ® by the second set of radial indentations set 45 degree from the cross recess. This Pozidriv ® design is intended to decrease the likelihood that the Pozidriv ® screwdriver will slip out, provide a greater driving surface, and decrease wear.
