The practical set includes all the necessary tools for quick and easy tire changes. There's no need to reset the torque wrench to 0. The torque value can remain permanently set, thanks to a patented, low-wear release system with a bending rod. A sturdy plastic case with a carrying handle and a custom-fit insert ensures safe transport and storage. For over 150 years, Stahlwille, a traditional German company from Wuppertal, has been known for tools that are appreciated worldwide for their excellent quality. No resetting to 0 is required, as the measuring element is only loaded during the tightening process. Quick adjustment is facilitated by an easy-to-use clamping lever in the handle. The ergonomically shaped, slip-resistant adjustment element features a thumb recess. An integrated magnifying glass is included in the reading window. The optimized palm grip allows for fatigue-free working. It also features a double-stop signal and a dual scale in Nm/ftlb. Continued loading after the release or loads against the functional direction do not affect the release mechanism, protecting it from damage. All sensitive parts are safeguarded by the robust steel tube housing. Calibration can be adjusted with the perfectControl calibration device or the calibration system without disassembly if necessary.
