Click-type torque wrench with 3/4" ratchet for 110-550 Nm (80-405 lbf·ft), with audible and tactile release, ±3% accuracy and traceable test certificate.

• Use: Controlled screw tightening in the range of 110 - 550 Nm / 80 - 405 lbf·ft, Adjustable, releasing and sturdy tubular torque wrench with integrated ratchet and with square drive for industry and the trades, Features: Classified as per DIN EN ISO 6789-2:2017 Type II Class A
• Adjusted to a maximum permissible +/-3 % deviation and thus with a greater precision than the standard-stipulated +/-4 %, Incl. traceable test certificate (DIN EN ISO 6789-2:2017), For controlled right- and left-hand tightening (square socket for direction change), 3/4" square drive through with pin lock, Robust, matt powder-coated tubular steel construction, with galvanized ratchet and high-quality plastic parts, New ergonomic handle, shaped according to the natural grip position of the hand, Clearly recognisable and tactile hand centring aid and calibration aid in the middle of the handle, Double scale Nm / lbf·ft and vernier are protected from abrasion and contamination by an enlarged viewing window, With vernier scale for Nm main scale for setting intermediate scale values
• Lbf-ft setting only via main scale, Vertical alignment of the scale, torque adjustment therefore suitable for left and right handers, Scale line positioned directly above the scale prevents reading errors (parallax errors), Unit labeling integrated in the scale frame and also protected by viewing windows, The precise release mechanism generates a distinct tactile and audible release signal when the set torque value is reached, Incl. roll away protection, prevents rolling away when the tool is put down
