History.
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).
The company was acquired by Snap-on in 1993, and it was officially renamed Snap-on Industrial Brands in 2011.
