ITW Shakeproof Group is a leading designer and manufacturer of value added, high quality engineered hardware solutions. Our History Known as ITW Shakeproof Group today, the company is the result of a 2010 merger of ITW businesses that have a long, rich history in the industrial hardware market. This history dates back to the 1920s, when two of ITW Shakeproof Group’s main product lines were created. Shakeproof was formed in 1923 when it introduced the Twisted Tooth Lock Washer. Bee Leitzke, established in 1929, was created through the merger of well-known hardware manufacturers Medalist Rein Leitzke and Hobbs. Together, these companies have decades of problem solving, product design and manufacturing experience which is demonstrated in the quality of the products you purchase.
