Product description: Tightening and loosening strongly tightened hex screws and nuts requires an enormous amount of force. With the leverage action from the Wiha ring ratchet open-end spanners, the user can easily open any fastening. The jaw end is also excellently suited for tightening screws and nuts. With 15° jaw positioning, the jaw end is perfect for working in confined spaces. Similarly, when working with the ring ratchet, the user benefits from the fine toothing with 72 teeth, offering a short return angle and highest comfort when working in confined spaces due to the double hex design. By simply turning around its own axis, it can be switched between right and left rotation. Made of high quality chrome vanadium steel, the ring ratchet open-end spanners are distinguished by their longevity and robustness, not the least thanks to their corrosion-resistant and easy to clean surface.
Standards: Based on DIN 3113
Application: For installation and mounting work. Eminently suitable for working in confined spaces.
