Design: Sturdy, compact, single-arm torque wrench, pre-settable according to scale and self-releasing. The accuracy remains consistent over tens of thousands of uses, as high-quality materials are used for all wear parts and the bending rod is only briefly loaded during operation. Housing and handle made of stable rectangular tubing. Scales can be adjusted. Left-hand torque by switching the insert tools. Without insert tool (basic model); compatible insert tools No. 657582 − 657950. Note: The guaranteed measurement accuracy of the torque applies only from the calibrated torque range according to DIN EN ISO 6789. Advantage: Ergonomically shaped 2K handle, resistant to aggressive liquids such as fuels, Skydrol, etc. Adjustment scale protected from dirt and damage by a viewing window. Quick, precise, and secure adjustment: pull the adjustment knob, set the desired value by turning, and secure by pressing. Easy movement of the adjustment knob, as no spring force needs to be overcome.
