Screwdriver usage

Date:Jun 09, 2020

Align the end of the screwdriver with a special shape to the top recess of the screw, fix it, and then start to rotate the handle.

According to the specification standard, the clockwise rotation is the tight fitting; the counterclockwise rotation is the loosening. (In rare cases, the opposite.)

Slotted screwdrivers can be used for Phillips screws. However, Phillips screws have a strong resistance to deformation.
