Stanley Proto tools have been designed and built in the United States for over a century, with workmanship and precision suited for the most demanding and unforgiving remote worksites—where dependability is a must. Strength and exceptional safety are the hallmark all Proto products, including torque wrenches, ratchets, sockets, screwdrivers and multipliers.

Proto's incomparable reliability in extreme conditions sets the industry standard for strength and safety.
