Safe: Tactile (quick-release) Acoustic (bending element) Quickly and securely set the desired torque value by turning the handle. Particularly slim design due to the spring-loaded pull sleeve for locking the adjustment values. Accuracy ± 2% of the scale value (6106-1CT: ± 4%) (in the direction of operation for right-hand tightening). For left-hand tightening, use our torque wrenches with a socket drive. Application: Engine area, gearbox, industry, machinery, model building. Comes with calibration certificate and serial number. DIN EN ISO 6789-2:2017, DIN 3120, ISO 1174-1. Made in Germany. Output: Square 6.3 mm (1/4 inch). Dimensions / Length: 256 mm. Net weight: 0.4 kg. Nm min-max: 4 - 40 Nm. Tolerance: 2%. Scale division (Nm): 0.4 Nm. Operating force min-max: 2.0 - 21.4 kg. Number of teeth: 20 (operating angle 18°). Head thickness a: 10.2 mm. Head width b: 24 mm. Outside of the DIN range, as the maximum torque value of the square indicated in standard 6789-1:2017 is exceeded. No more back-turning: Long-term durability tests have shown that with HAZET torque wrenches from the 5000 and 6000 series, back-turning to the smallest scale value is not necessary.
