The practical set includes all the necessary tools for quick and easy tire changes. There is no need to reset the torque wrench to 0. The torque value can remain permanently set, thanks to the 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 has been a German traditional company from Wuppertal known for tools that are valued 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-operate clamping lever on the handle. The ergonomically shaped, slip-resistant adjusting element features a thumb recess. An integrated magnifying glass is included in the reading window. The optimized palm grip allows for fatigue-free working. Double stop signal. Dual scale Nm/ftlb. Continued loading after release or loads against the functional direction do not affect the release mechanism, protecting it from damage. All sensitive parts are protected by the robust steel tube housing. Calibration can be adjusted with the perfectControl calibration device or the calibration system if necessary, without disassembly.
