Clutch Type
I tried to add clutch type of screwdriver to the drive type box but doesn't show right. Can someone help? Thanks PCMentor (talk) 12:20, 23 January 2009 (UTC)

Slotted
Why is this even a separate article? They should be merged at the very least, with Slotted becoming a redirect. Anybody oppose this? thadius856talk 00:22, 5 January 2007 (UTC)


 * The information in Slotted is already covered in Screw, which is really where it belongs (since the focus of Slotted is on the type of screw). I think Slotted should just be deleted.  The article title is counter-intuitive anyways, as I can imagine someone searching for "slotted screw" or "slotted screwdriver" but not just "slotted" expecting to find either the screw or the screwdriver. If anything, I'd bring the photo of the slotted screwdriver into this article. PubliusFL 18:35, 5 January 2007 (UTC)

New type of Chinese screw head
I have seen a new(?) type of screw head, in a Chinese electric transformer,

but I have not seen the screwdriver.

The head of the screw is like an H in a 0.

The hollow part is the upper and lower "empty" parts of the H.

The screw driver probably inserts like a fork,

like a Y maybe, or like a U.

I don't own a camera, if you see one please post a picture,

to make the article more complete. —Preceding unsigned comment added by 85.75.35.58 (talk • contribs)

There is nothing new about these. It is a common type of security screw, frequently seen in electrical kettles or some types of burglar alarm. Our local shopping centre uses them to prevent kids taking the light switches apart. The illustration box in the main page refers to these as "spanner head", but I have also seen them refered to as "dual pin" or "split tool" heads. The design does not seem to be patented, and as such there is no controlling influence in the selection of a name.

They are now far less common in Europe in the last decades since the advent of anti-tamper Torx heads, which can be driven with higher torque. Brunnian (talk) 15:49, 18 August 2008 (UTC)

Shape chart
Where's the shape chart mentioned on the Phillips screw picture? --Dexter_prog (talk • contribs • count ) @ 22:10, 1 March 2010 (UTC)

Invented in 1907?
From paragraph six or seven of the History section: "One of the most popular new designs of the screwdriver was made by Canadian P.L. Robertson, who inadvertently invented the screwdriver when he patented the first socket-headed screw in 1907." How could Robertson have invented the screwdriver in 1907 if, as the article states, the screwdriver "was invented in Germany in the late fifteenth century"? --Badger151 (talk) 00:51, 2 July 2010 (UTC)

Ergonomics
I have added a brief mention of ergonomics to the handle section, which could be expanded further. I have also added the offset screwdriver to the handle section, and an image would be idea here. Anyone? Peterlewis (talk) 15:51, 4 June 2012 (UTC)

Phillips Screwdriver sizes
The sizes of Phillips screwdrivers now (in 2012) range from at least #0000 to #4 (not #00 to #3 as the article currently states). I suppose it would be a copyright infringement to scan a picture of my screwdriver set and post it, but a description of it, showing a #000 bit for both Phillips and Posidriv, can be found at http://www.olympiatools.com, search for category "iWork", item 76-523.

A Sears Craftsman Phillips #0000 is for sale at http://www.sears.com/craftsman-0000-x-1-in-screwdriver/p-00941645000P and there's a #4 for sale at http://www.sears.com/craftsman-professional-no-4-x-8-in-screwdriver-phillips/p-00947188000P Gordonburditt (talk) 08:25, 20 November 2012 (UTC)
