Stanley® Proto® was the first company to market the combination wrench in the United States in 1933. Since then, we have greatly expanded our line of wrenches and developed a range of new products. Our line now includes standard, extra long and short combination, flex head, open end, angle head, box, deep offset box, ratcheting box, obstruction, adjustable, flare nut, striking, slugging, construction, spanner and pipe wrenches. In other words, we have a wrench for nearly any fastener.
