When a Phillips is not a Phillips - Plus So Much More!
A Continuation of Screws and Drives
by Egon Pavlis, Biomedtronix Inc.
With overwhelming response to my preceding "ible" titled "When a Phillips is not a Phillips? - Cross-head, Cross-Point, Cruciform, Square Drive Screws and Drivers" and this logical expansion follows. Readers requested information on all - recessed screw drives including security, especially the tougher ones to find. Well, here they are.
This article contains a lot of information presented from company websites, catalogues and brochures and so 'may be biased' to highlight their drive qualities. There are some advantages and disadvantages of some drive types. This "ible" is not intended to present one drive superior over another as each has desirable qualities. Maybe it will be the definitive guide with your help it could get close.
If you disagree with any of the information or if I missed a related drive you know of, please let me know where I can validate the information. Miss-information, incorrect illustrations, screwed up usage of terms on the Internet and elsewhere is rampant and part of the problem created by so many drives.
Should you have relevant information, especially verifiable or with web links, clear pictures etc to add, correct or improve the project please email it to me so I can follow-up on it.
Please refer to the Step # when leaving comments or questions to that specific drive types.

- Notes about project layout
Icon patterns of each screw type are a view of the screw head, straight on. They can best be visualized if you imagine the screw head is used as a rubber stamp with a black inkpad. The screw head fingerprint result transferred onto white paper should resemble the icon. The drive of course is usually, but not always, an inverse of this. Occasionally gray is used in some icons to indicate detail at a different level, one that would also not touch the black in the print, but requires the detail highlighted.
A few types are grouped at the far end of the 'ible', these include Combo Drives, Security Key Drives and Gamer Drives.
