The ITW Difference

In 1912, Chicago financier Byron Smith met a group of investors looking to improve gear grinding. From that encounter, Illinois Tool Works Inc. (ITW) was born. More than a century later, ITW is still fueled by a spirit of innovation, and a determination to deliver specialized expertise and value-added products that meet the needs of customers worldwide.

ITW Brands was formed in 1992 to meet the growing demand from consumers and remodeling contractors for high-quality home improvement and do-it-yourselfer construction products. ITW Brands' products are used by construction and building professionals worldwide and feature some of the most well-known and best trusted brand names in the industry.
