Start with 16, add little.

Fedor Novikov
each screwdriver has its own concept of setting the force, select it empirically. If there is too much, then you can ruin the screw or bit or fastened parts.

To drive screws into a concrete wall, you first need to drill holes in it, drive dowels into them, and then screw the screws with any effort. You can and generally it will be done with a screwdriver. And you can’t screw anything into concrete right away with any effort.

Operate by the empirical method (in Russian, the method of scientific poke) Concrete is different everywhere. If in one house it knocked a little, it already fell down, then in another sparks fly
