Controlled torque wrench in the most common range of 20-100 N·m / 15-75 lbf·ft (reference for screws M7-10.9 to M24-8.8, M30-5.6). Adjustable, releasing, and robust pipe torque wrench with a socket drive for industrial and manual use. Classified according to DIN EN ISO 6789:2003 Type II Class A, with a traceable factory certificate. Calibrated to an allowable deviation of +/- 3% or better. The standard requirement (+/- 4%) is exceeded for your safety. For controlled tightening in both clockwise and counterclockwise directions. Robust, satin-chromed steel tube construction, with a phosphated socket drive (16 mm) and high-quality plastic parts. Ergonomically shaped 2-component plastic handle with calibration aid. Switchable between main scale N·m and secondary scale lbf·ft to avoid reading errors when setting the desired torque. Features a micrometer scale for the N·m main scale to set intermediate scale values. The release system generates a tactile and audible release signal. Ergonomic torque adjustment system with indicator symbol. Quick adjustment possible with a socket screwdriver, not included. Secured adjustment calibration system. Factory calibration socket size: 32 mm (16 mm). Operation only with plug-in tools with a uniform socket size - otherwise, value shifts may occur. Depending on the tool used, work can be done either forward (e.g., with a socket wrench) or sideways (e.g., with a ratchet and socket insert). Patent pending.
