2-component handle for improved feel. Simplified locking for adjusting the torque value. Viewing window for visual checking of the locking. Four colored coding rings (red, yellow, green, black) for markings in the case of personalization or special workflows. Without signal transmitter. Accuracy ± 2% of the scale value (in direction of actuation for right-hand tightening). For left-hand tightening, use our torque wrenches with insert tool. HiPer fine-tooth reversible ratchet in models 6121-1CT, 6122-1CT, 6123-1CT (90 teeth, 4° operating angle). High-precision premium torque tools for the highest demands. Hard chrome-plated steel tube - slim, but very sturdy and wear-resistant. Secure storage in a safe box with display window. Safety features include haptic (close-gap release) and audible ("click" sound). User-friendly reversible ratchet. Service-friendly (do-it-yourself repair sets for ratchets available). Integrated shift lever. Easy and safe adjustment of the desired torque value by turning the handle. Knob for additionally locking the set value. Ergonomically shaped handle with collar reduces the risk of slipping off and injury. Accuracy - fine scale graduation.
