2-component grip for improved haptics. Simplified locking mechanism for adjusting the torque value. Viewing window for visual control of the locking. Four colored coding rings (red, yellow, green, black) for marking in personalizations or special workflows. Scaled according to US standards in lbf.ft with ± 3% accuracy from the scale value (in the direction of operation for right-hand tightening). For left-hand tightening, use our torque wrenches with a square drive. Safe: tactile (short release) and acoustic (snap element). Quickly and securely set the desired torque value by turning the handle. HiPer fine-tooth ratchet in 6127-1CT (90 teeth, 4° operating angle). Knob for additional locking of the setting. Secure storage in a safe box with a viewing window. Comes with a calibration certificate and serial number. DIN EN ISO 6789-2:2017, DIN 3120, ISO 1174-1. Made in Germany. Output: Square 20 mm (3/4 inch). Dimensions / Length: 1284 mm. Net weight: 6.42 kg. Nm min-max: 162.7 - 813.5 Nm. lbf min-max: 120 - 600 lbf.ft. Tolerance: 3%. Scale division (lbf.ft): 2 lbf.ft. Effective length of the torque wrench min-max l1 mm: 1182.70 - 1158.70 Nm. Operating force min-max kg: 14.0 - 71.6 kg. Number of teeth: 32 (operating angle 11.25°). Head thickness a: 28.5 mm. Head width b: 64 mm. No more back-turning: In long-term durability tests, it has been proven that for HAZET torque wrenches in the 5000 and 6000 series, back-turning to the smallest scale value is not necessary.
