The double-square drive is two squares superimposed at 45° rotation, forming an 8-pointed star. The design is similar to a square drive (Robertson), but can be engaged at more frequent angles by the driver bit. 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. The manufacturing process for Pozidriv screwdriver bits requires a slightly more complex cutter than that for Phillips, however both can be manufactured in four cuts from a tapered blank.

The Phillips screw drive (specified as an ANSI Type I Cross Recess [9] and type H in ISO documentation) was created by John P. Thompson, who, after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. [10] [11] Phillips is credited with forming a company ( Phillips Screw Company), improving the design, and promoting the adoption of his product. [10] The original 1932 patent [12] expired in 1966, but the Phillips Screw Company continued to develop improved designs. [10] ASTER System". www.lisi-aerospace.com (in French).

The Phillips Screw Company must inspect and approve any punches, bits, and screws before they are cleared for production. Along with this "all licensees must submit samples regularly to ensure that the strict quality standards are maintained". [38] Solid modeling is used for the design of the punches, bits, and screws. Files are sent over to manufacturers containing these models so that there is no miscommunication and all the parts are the same across the board.I just wanted to say a massive thank you for all your help yesterday. I really appreciate it and will certainly be using you again for future installation products. (Amy) Some screws have heads designed to accommodate more than one kind of driver, sometimes referred to as combo-head or combi-head. The most common of these are a combination of a slotted/Phillips head.
