Application: Controlled bolt tightening in the range of 80 - 400 Nm / 60 - 300 lbf-ft. Adjustable, releasing, and robust tubular torque spanner with rectangular receptacle for industry and trades.

Design: Classified according to DIN EN ISO 6789-2:2017 Type II Class A, including traceable test certificate. Calibrated to a maximum permissible deviation of +/- 3%, thus more precise than the +/- 4% required by the standard. For controlled right and left-hand tightening. Robust, painted tubular steel construction, with galvanised rectangular holder (14x18 mm) and high-quality plastic parts. Ergonomically shaped plastic handle with calibration aid.

Switchover between vernier main scale Nm and secondary scale lbf-ft to avoid reading errors when setting the desired torque. With micrometer scale for Nm main scale for setting intermediate scale values. Jump-off system produces a clear tactile and audible trigger signal. Ergonomic system for torque adjustment with indicator symbol. Secured adjustment system.

Factory calibration gauge: 25 mm (14x18 mm). Operation only with insertion tools with uniform gauge; otherwise, there may be value shifts. Depending on the tool insert, work can be carried out either to the front (e.g., open-ended socket spanner) or to the side (e.g., reversible ratchet and socket spanner insert).
