Forbes has a great article entitled The Taming of the Screw which tells of a new redesign of the screw. “The humble screw has changed little in 2,000 years, until a stubborn engineer at Illinois Tool Works came up with a fascinating new twist.” – Very cool! Reminds me of a great book I read a year or so back: One Good Turn: A Natural History of the Screwdriver and the Screw which I highly recommend. It’s far more interesting than it sounds. I promise.
