According to US standard scale division in lbf.ft ± 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) and acoustic (break element). Setting the desired torque value quickly and securely by turning the handle. HiPer fine-tooth ratchet in 6127-1CT (90 teeth ∙ 4° operating angle). Control 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 10 mm (3/8 inch). Dimensions / Length: 333 mm. Net weight: 0.56 kg. Nm min-max: 6.8 - 54.2 Nm. lbf min-max: 5 - 40 lbf.ft. Tolerance: 3%. Scale division (lbf.ft): 0.5 lbf.ft. Effective length of the torque wrench min-max l1 mm: 264.52 - 254.02 Nm. Operating force min-max kg: 2.6 - 21.8 kg. Number of teeth: 30 (operating angle 12°). Head thickness a: 14.5 mm. Head width b: 32 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.
