J.H. Williams Tool Group
Snap-on Industrial Brands, historically the J.H. Williams Tool Group, is a division of American hand tool manufacturer Snap-on that makes and distributes tools to industrial markets. In addition to the Williams brand from which it originated, the group includes Bahco and CDI Torque Products.
In 1882, James Harvey Williams and Matthew Diamond founded Williams & Diamond in Flushing, Queens, a drop forging business. The business was relocated to Brooklyn in 1884 and took the name J.H. Williams & Co in 1887. The company was one of the first to offer mass-produced drop-forged hand tools.  A second factory was opened in Buffalo, New York in 1914 (now the site of General Motors' Tonawanda Engine plant).
