Illinois Tool Works Inc
A maker of industrial tools, equipment and specialty products, ITW builds everything from welding gear (Miller, Hobart) and food-service equipment to construction fasteners and testing machines used by manufacturers worldwide. It started in 1912 when Chicago financier Byron L. Smith answered a newspaper ad seeking tool inventors and opened a small Chicago machine shop. Today the company runs through a famously decentralized "80/20" approach, and its Paslode brand helped invent the cordless nail gun that construction crews still use.
