Opening tightly fastened screws requires great force. With the leverage action from Wiha’s ring ratchet open-ended spanner, 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. The right or left rotation can be variably adjusted by the integrated switching lever. 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. The set includes the 12 most commonly used sizes from 8 to 19 mm, neatly stored in a convenient holder. The holder can be opened with a single hand to remove the appropriate size. The non-slip surface finish ensures a strong grip, even in oily or wet work situations.
