The Phillips Screw Company owns the licensed product that is the Mortorq spiral drive system. 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.

Line Head and Line Recess screw drives are Japanese systems with male, female and tamper-resistant configurations. [72]

This type is usually found in cheaply-made roofing bolts and the like, where a thread of 5mm (0.20in) or above has a large flattened pan head. The advantage is that they provide some measure of redundancy: should one slot be deformed in service, the second may still be used. Screw Holding Screw Driver" (PDF). Audiocraft Magazine: 7.

PH) (PZ) ISO 8764 PH drivers [31] are nearly identical to JIS B 1012 drivers. ISO 8764 has superseded JIS B 1012 in Japan as well as being used in many other countries. The standard specifies that drivers and bits are to be marked with a "PH" or "PZ" followed by the size number (000, 00, 0, 1, 2, 3), though not all manufacturers do this. [32] The 12-spline flange screw drive has twelve splines in the fastener and tool. It consists of 12 equally spaced protrusions, each with a 60° angle. It is achieved overlaying 4 equilateral triangles, each one rotated 30° over the previous one. The spline drive was part of the obsolete, U.S-designed Optimum Metric Fastener System and was defined by ASTM B18.2.7.1M, which was withdrawn in 2011, [81] making the spline drive obsolescent.
