Phillips Screwdriver

Name for patented cross (+) shaped screwdriver that is self centering. Comes in numerical sizes, #0 (tiny) to #2 (large). Occasionally in larger sizes. See also Posidriv and Reed and Prince.

Phillips screw or screwdriver: The Phillips screw or screwdriver (you can't have one without the other) was actually the invention of J. P. Thompson, who couldn't find anyone willing to manufacture the screws.

Henry F. Phillips (2066484 -click here for text of patent) of Portland, Ore., purchased the rights for the recessed crosshead design and obtained patent protection. He entered into a business arrangement with the American Screw Co. in Providence, R.I., which was better equipped to manufacture, the product. Phillips and the American Screw Co. prospered when automobile makers universally switched to Phillips screws.

A method of attaching face frame (and outer) members where a Jig is used to drill a Pilot for a Screw at an acute angle.

[Pocket screw - bottom of the angled "mortise" is flat and a flat bottom rather than a conical? Charlie B's comment]
