The 72-toothed inner ring made of high-alloy special steel allows the drive to be activated with a lever movement of 5°. The transmittable torques exceed DIN/ISO standards. Shafts made of CrV steel feature optimum surface protection: 2x nickel-plated and 1x matt chrome-plated. Wrench widths are clearly readable using laser marking methods. The head, which is angled by 15° on all sides, cannot be turned. This key type includes a lever switch for clockwise and counterclockwise rotation, making it ideal for screwing to flat surfaces. It includes one extra long piece each in sizes SW 8, 10, 13, 16, 17, 18, and 19 mm, all housed in a sturdy powder-coated steel box.
