Riddled with inaccuracies, as usual for The Register.
A "Brummie Screwdriver" is NOT a common-or-garden clawhammer, but rather the old-fashioned cast-iron Stillson's-type plumber's monkey-wrench, 15-18 inches long, traditionally painted red on the handle.
The hammering face is usually the back of the monkey-screw housing.
Also, picture number 2 *is* a screw, specifically a "Machine Screw".
The bolt, which the author seems to have confused this with, is easily distinguished by a smooth, threadless section near the head. You can *use* a machine screw as a bolt, but there are penalties for doing so without using a bushing as any proper engineer would know.
