Hollow shaft magnetic nut driver for long bolts, studs or threaded rod. Klein Tools was founded in the USA in 1857. We are continually expanding the manufacture of tools here in the USA. In 2003 we opened a plant in Elk Grove Village, Illinois that supplies forgings made from high quality, U.S. made steel. In 2006 we opened a new corporate headquarters and screwdriver plant in Lincolnshire, Illinois. In 2008 we purchased Heritage Cutlery in Bolivar, New York where we manufacture high quality scissors and other cutlery products. In 2010 we opened an Advanced Manufacturing Technology Center in Mansfield, Texas where we manufacture pliers and wire strippers. Investment in four manufacturing plants in the USA in the last 10 years is convincing evidence that we are committed to manufacturing in the USA.
