Pioneering the idea of interchangeable sockets and wrench handles, Joseph Johnson together with William Seidemann, formed the Snap-on Wrench Company in 1920. The company manufactured and marketed ten sockets that would "snap on" to five interchangeable handles, a concept that revolutionized the tool industry. Snap-on has continued its innovative leadership across an ever-expanding line of products to this day.
Snap-on today supports serious professionals in critical industries — inside and outside vehicle repair — by delivering a broad array of productivity solutions that make work easier, including tools, equipment, diagnostics, repair information and systems solutions.

Today, Snap-on is a $3.4 billion, S&P 500 company headquartered in Kenosha, Wisconsin, offering products and services that are available around the world.
