- Torque. It characterizes the effort with which the apparatus is able to work. This value affects the choice of material and the size of the mounting devices with which this tool can work. For homework, a torque of 25-30 Nm is enough.
- Reverse. Its presence is necessary when the network home screwdriver is needed not only to tighten the fasteners, but also to remove them.
