According to US standard scale division in lbf.ft with ± 3% accuracy from the scale value (in the direction of operation for right-hand torque). For left-hand torque, use our torque wrenches with a square drive. Safe: tactile (short release), 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. Safe 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 12.5 mm (1/2 inch). Dimensions / Length: 545 mm. Net weight: 1.3 kg. Nm min-max: 54.2 - 271.2 Nm. lbf min-max: 40 - 200 lbf.ft. Tolerance: 3%. Scale division (lbf.ft): 1 lbf.ft. Effective length of the torque wrench min-max l1 mm: 450.47 - 427.91 Nm. Operating force min-max kg: 12.3 - 64.6 kg. Number of teeth: 32 (operating angle 11.25°). Head thickness a: 19.6 mm. Head width b: 44 mm. No more resetting: In long-term durability tests, it has been proven that resetting to the smallest scale value is not necessary for HAZET torque wrenches of the 5000 and 6000 series.
