Opening tightly fastened screws requires a tremendous amount of force. With Wiha's ratchet ring wrenches, users can easily loosen any screw thanks to the leverage effect. Additionally, the open end is excellent for countering screws and nuts. With a jaw angle of 15°, the open end is perfect for working in tight spaces. Even when using the ratchet, users benefit from the double hex and the fine-toothed mechanism with 72 teeth, providing a short return angle and maximum comfort in confined work environments. By simply turning the wrench around its own axis, users can switch between clockwise and counterclockwise operation. Made from high-quality chrome vanadium steel, the ratchet ring wrenches are designed for durability and robustness, not least due to their corrosion-resistant and easy-to-clean surface. The set includes the seven most common sizes (8, 10, 12, 13, 15, 17, 19 mm), neatly stored in a practical holder. The holder can be opened with just one hand to easily retrieve the desired size. The textured surface ensures a strong grip, even in oily or wet working conditions.
