The Pozidriv is an improved version of the Phillips screw drive. The Pozidriv was patented by GKN Screws and Fasteners in 1962. It was designed to allow more torque to be applied and greater engagement than Phillips drives. As a result, the Pozidriv is less likely to cam out. It is similar to, and compatible with, the Supadriv screw drive.
Pozidriv screwdrivers are often designated using the letters "PZ". Pozidriv screws have a set of radial indentations (tick marks) set at 45° from the main cross recess on the head of the screw, which makes them visually distinct from Phillips screws.
While a Phillips screwdriver has slightly tapered flanks, a pointed tip, and rounded corners, a Pozidriv screwdriver has parallel flanks, a blunt tip, and additional smaller ribs at 45° to the main slots. Pozidriv and Phillips are broadly interchangeable, but may cause damage if incorrectly used. While Pozidriv screwdrivers fit Phillips screws, they may slip or tear out the Phillips screw head. Conversely, while Phillips screwdrivers will loosely fit and turn Pozidriv screws, they will cam out if enough torque is applied, potentially damaging the screw head or screwdriver.

A screwdriver is a tool, manual or powered, used for screwing (installing) and unscrewing (removing) screws. A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. The earliest documented screwdrivers were used in the late Middle Ages. They were probably invented in the late 15th century, either in Germany or France.
