Don't let the name fool you -- Illinois Tool Works (ITW) hammers out a lot more than just tools. With some 625 separate companies in 44 nations, ITW makes a range of products used in the automotive, construction, paper products, and food and beverage industries. The company's engineered products segment offers fasteners, nail guns, industrial adhesives, and automotive transmission components. The specialty systems unit's products include paint application equipment and welding machines. Although ITW focuses on buying small, often niche, companies and then making them more efficient, the company has sold its consumer products holdings (appliances and cookware, exercise equipment, and ceramic tile).
