A torque wrench should ensure that a screw or mother is put on with the correct torque. This torque is set on a scale before assembly. There is a spring mechanism inside the key. The force is generated via the pretended spring, with which the desired and set torque is applied to the screw or mother. The question arises which torque is the right and safe? Here our little overview with guidelines for the most important screw connections helps.

Important: These are explicitly guidelines. If in doubt, a look at the manufacturer’s side helps to find more information about the perfect tightening moment.

Let’s go with you 250 grams Light tool from Topeak. According to the manufacturer, the maximum torque of this compact tool is included 6 nm. This is sufficient for the most important connections in everyday life. At crank & Co., however, a part with more boom is needed. Nice: the ratchet can not only be equipped with the torque attachment. Because there is one for this set Chainnant as well as an extension to increase the leverage effect if necessary.

So it is also completely sufficient for home use. Here the desired torque is set via a separate key. Danger: The Lezyne tool cannot solve screw connections. The Pocket Torque Drive in a soft case with the six most important inbus bits and two Torx attachments.

Even a few grams lighter than Lezyne is Birzman’s mobile torque wrench. The scales show just 142 grams here. According to the manufacturer, the tool even creates a maximum tightening moment of 10 nm. That is not enough for crank & Co., but for everything else you are on the safe side with the Birzman. The desired value can be set and checked using a so -called towing pointer. The screws are then tightened over a finger lever. This is a tricky thing for less filigree hands. That only 2 centimeters short handle of Must be extended in order to be able to screw accurately. The right tool is included. Also lie six bits (inhex and Torx) in the plastic box.

This torque kit of Silca is located in the price range of a workshop torque key. But for Almost 150 euros Hobby screwdrivers get a noble and high -quality processed tool in a waxed case.

With a handle length of ten centimeters, the tool lies safely in the hand. An extension is also included in the scope of delivery as the Ten most important bits (inhex, Torx, PH). The connections between ratchets, torque places and the bits are at the all fixed magnetically.

It could hardly be more compact. At the BIKEBROZ tool, the right bits are in the T-handle and can be folded out and removed at the push of a button. The most important sizes (Torx, inhex, slot and ph) are included. A torque of A maximum of 8 nm promise the three brothers who gave Bikebroz their name. Unusual, but helpful: If the torque is reached in front of the set, you get not only a mechanical, but also an acoustic signal. The manufacturer specifies the tolerance at around 6 percent. The Is about 17 centimeters long And with it still stowed in jersey or saddle pocket.
