Application: Particularly suitable for industrial applications and use in series production. Especially handy due to its short design. Universally applicable with a holder for insert tools. Accuracy ± 2 % (6391-10: 6 %) of the set value (in the direction of actuation). Usable for right and left threads by rotating the insert tool. Plug connection for holding insert tools. Fixed adjustable value. Especially suitable for use in industrial series production. Setting the desired torque value with combination wrench 6399 in conjunction with HAZET testing device 7901E, 7902E, 7903E, or another suitable device. All wrenches in this series (HAZET 6391-6392) are without adjustment scale. Comes with calibration certificate and serial number DIN EN ISO 6789-2:2017. Made in Germany. Drive: Insert square 9 x 12 mm. Dimensions / Length: 124 mm. Nm min-max: 1 - 10 Nm. Tolerance: 6 %. Effective length of the torque wrench min-max l1 mm: 121.00 - 121.00 Nm. Actuation force min-max kg: 0.8 - 8.4 kg. Dimension of the adjustment tool l2: 19.5 mm. Head thickness a: 17 mm. Head width b: 22 mm. No more back-turning: In long-term durability tests, it has been proven that for HAZET torque wrenches of the 5000 and 6000 series, back-turning to the smallest scale value is not necessary.
