The twisting wrench is your solution for twisting multiple sizes of square bar stock with one tool.
The tool is designed to twist 5 different sizes of bar stock, including 3/8″, 7/16″, 1/2″, 9/16″ and 5/8″. The larger sizes are on the handle ends to give added leverage. The smaller sizes are in the center for more delicate twisting projects. The tool is made of 1075 spring steel, .312″ thick. It is recommended that this tool be used with hot iron. However, tweaking can be done on warm iron and twists can be made on smaller sizes cold.
