Heritage & History
Proto was founded in 1907 in Los Angeles as the Plomb Tool Company, manufacturing professional hand tools for the California trades and industrial market. The company became one of the early American industrial tool makers, developing reputation in aerospace, automotive, and manufacturing industries where tool quality directly affects productivity and safety. Plomb became Proto in later decades, and the company eventually became a division of Stanley Black and Decker.
Proto's industrial positioning distinguishes it from consumer tool brands: Proto tools are made to meet industrial specifications for professional use in demanding environments. The tools are available through industrial distributors and carry industrial catalogs specifying torque capacities, alloy specifications, and finish standards that consumer tools do not document. Professional mechanics, aerospace technicians, and plant maintenance teams have relied on Proto tools for over a century because the company has never built tools for anyone other than professionals.
