70-350 Nm 1/2" Steel: CrV50Bv30 Used for working with right-hand thread. "Delo Tekhniki" torque wrenches are reliable and accurate tools designed for assembling critical connections with a specified torque. The wrenches are calibrated and tested. The error in the wrench's operation does not exceed 4%. The wrench should be loaded smoothly and evenly. Achieving the specified torque is accompanied by a noticeable click and a slight idle stroke. Once the specified torque is reached, it is necessary to stop further loading of the wrench. If the torque wrench is new or has not been used for a long time, several operations should be performed at a low torque beforehand. Attention! The tool should be stored in an unloaded state. To do this, fully loosen the handle of the wrench counterclockwise. "Delo Tekhniki" torque wrenches are officially included in the register of measuring instruments: Registration number 80338-20, order of Rosstandart № 2244 dated December 28, 2020, approving the type of measuring instrument.
