The key is designed to release screws with a specific number of pages, such as six or 12. The key design allows it to be modified to turn the screw even in tight spaces where the movement is limited. The key can be bent at both ends at a certain angle to facilitate the rotation of the screws. The angle and twisting the key movement applies a special force with less effort at the end of the user. It also creates a stronger grip around the screw, while if the user tried to use his bare hands, his fingers would simply slip from the screw.
