How tight is tight enough? This question decides everything when screwing. Too loose and the screw loosens under load. Too tight and the thread breaks. With a torque spanner from Kraftwerk, you can hit the sweet spot between "holds" and "breaks".
A torque spanner is required wherever a manufacturer specifies a specific tightening value in Newton metres (Nm). A defined torque ensures that wheel nuts or motorbike bolts hold and nothing is overloaded. The trade knows: «After tight comes from». If you tighten by feel, you are almost always wrong.
Kraftwerk, the Swiss tool brand from Mönchaltorf that has been on the market since 1979, has revised its Click torque spanner series and is launching new models. They cover a range from one to 1000 Nm. This is sufficient for precision mechanics and bicycle cockpits through to three-quarter inch chunks for lorry wheel nuts and heavy industrial applications.
Variants for all types of work
The 3/8″ variant for 10 to 50 Nm is suitable for entry-level bicycle and smaller engine work.
The 1/2″ spanner with 40 to 200 Nm is suitable for most car and motorbike screwdriving work, including wheel nuts on cars.
For heavy-duty applications, such as employees working on lorries, agricultural machinery or in industrial assembly, the 3/4″ model with 100 to 600 Nm is the right choice.
Classic click operation
The operation follows the familiar click principle: You set the target value using the main and fine scales. As soon as you reach the set torque when tightening, the spanner emits a clearly audible and perceptible click signal. A window display shows the values in Newton metres. A mechanical lock on the handle prevents the set value from being adjusted during work.
Calibrated for precise work
All Kraftwerk models are calibrated at the factory in accordance with DIN EN ISO 6789-1:2017, with a tolerance of ± 3 per cent. According to the manufacturer, each spanner comes with a calibration certificate. The smaller models work with a 72-tooth ratchet head, which enables a small swivelling angle of around five degrees in confined spaces. The large 3/4″ variants rely on a more powerful 48-tooth mechanism for higher loads. Each spanner comes in its own case.
The steel body and the handle, which should remain non-slip in oily hands, are suitable for professional use, according to the manufacturer. Important to know: The spanners only tighten on the right. Left-hand threads with torque require a different tool.
According to the manufacturer, repair kits are available for all models. This allows wearing parts to be replaced and the spanner to be recalibrated after a while. Tools in this price range rarely offer this.
