The torque wrench is very easy to handle and wonderfully suited to switch twice a year on car wheels. In the Storage Box 17 mm and 19 mm nuts lie. Also for 21 mm, a storage tray is provided, just a pity that there is no 21mm nut to, because that I have used for the studs of my Toyota Auris and had still to buy extra. Packt Just another 21mm nut to, then there are also 5 star.
