Design: Sturdy, compact, single-arm torque wrench, pre-adjustable according to scale and self-releasing. The accuracy remains consistent over tens of thousands of applications, as high-quality materials are used for all wear parts and the bending rod is only briefly loaded during operation. Housing and handle made from durable rectangular tubing. Scales can be readjusted. Left-hand tightening by repositioning 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. The adjustment scale is protected from dirt and damage by a viewing window. Quick, precise, and secure adjustment: pull the adjustment knob, turn to set the desired value, and press to secure. Easy movement of the adjustment knob, as no spring force needs to be overcome.
