This complete supply line control ensures that their high standards shape the end product along every step of the process. Some of Stahlwille's specialty products include FastRatch ratchet wrenches, cadmium-free High Performance Quality (HPQ) sockets suitable for use on titanium fasteners, MANOSKOP® and Sensotork® Torque Wrenches, and perfectControl® torque calibration and adjustment units. Many of their products are FOD certified, permitting them to be used in the tightly-regulated aerospace sector.
