Design: Handy and very compact one-arm torque wrench, adjustable via scale and self-releasing. Extremely high repeat accuracy, as only high-quality materials are used and wear parts such as compression springs are specially pre-treated or sorted. By switching the ratchet, both right-hand and left-hand tightening are possible. With a permanently built-in switchable ratchet for right and left tightening. Measurement units: Nm. Note: Calibration is only possible for right-hand tightening. The guaranteed measurement accuracy of the torque is only applicable from the calibrated torque range according to DIN EN ISO 6789.
