History
Klein Tools was founded in 1857 in Chicago, Illinois by German immigrant Mathias Klein. The first tool Klein made was a pair of side-cutting pliers for a telegraph lineman. The company grew as the telegraph and eventually telephone and electrical industries grew after the Civil War by adding 100 types of pliers in the 1910s. From the 1960s-1980s, the company expanded their product line to include leather and canvas products, occupational safety equipment, hex key wrenches, screwdrivers, nut drivers, as well as electrical terminals and connectors. Along the way, Klein acquired the R.H. Buhrke Company of Fort Smith, Arkansas in 1968 and the Vaco Products Company of Jonesville, Michigan in 1986. Also in the mid 1980s, the company started manufacturing adjustable wrenches in the US, which they had previously been purchasing from a Japanese supplier.

Klein Tools built a drop forging plant in Moran, Kansas and distribution center in Cedar Rapids, Iowa before the 1990s. The company added an affiliate, Klein Connection, to help ensure a wider distribution of Klein products. Klein Connection is an e-commerce website.

In December 2011, the company announced that it was closing its plants in Skokie and Roselle, and moving their operations to Texas. Later that year, 2011, they opened their new advanced manufacturing facility in Mansfield, Texas. In 2014, they opened their new heat-treating facility and announced plans to expand on their 100 acres in Mansfield. In 2015, Klein added another 300,000 sf of plastic injection molding and machining, and in 2020 added an additional 270,000 sq. ft. Distribution Center. In 2021, Klein Tools moved its corporate headquarters to Mansfield, TX. The company is still owned and managed by members of the Klein family.
