I ordered this key when changing a wheel, the screws do not have to attract more "by feel". Last year me a screw is torn because I had "to well-intentioned", the boring of the thread was then not really cheap. Too much torque can permanently damage the rim or the hub. And what can happen when too little tightening force, it does not want to think about it. It should therefore be the proper torque and to achieve the 25-Euro-parts from the hardware store seemed simply not trustworthy enough. Grab this rattling things with their roughly punched sets times, then you will understand why I do not call them "instruments" and would depend my life on it. It was the Proxxon key with its 150 positive reviews and I include myself also completely: he acts wertig, has an engraved serial number is apparently calibrated, well packaged, is great in the hand and triggers (felt) every time the same. Amazing the way, how little are strictly 120 Nm, I had been attracted much too tight all bolts ... Meaningful product so that pays off because you will be so hopefully use it for many years.
SINGLE BUT: despite the right / left switch the torque wrench according to instruction should NOT be used to loosen the wheel nuts, but so you need a separate key, such as these here üssel / dp / B00BGT6YJ0 / ref = cm_cr_pr_product_top What sense thus the switch should have, she will not reveal to me, so I subtract one point.
AND: Do not forget a matching (long!) Nuss mitzubestellen, eg this 17er here for most German cars; psc = 1
Tip1: Take care that you do not have to hear the crack when reaching the set torque and then immediately stop further press! Because the key is very long, you might otherwise stop a screw easily. TIP 2: Reset After working on the torque wrench to the minimum of 40 Nm, so that the spring lasts a long time.
