Unscrewing slotted and cross screws

After some time the screws are rusted so badly that they can not be easy to turn a screwdriver. At Phillips screws even if not very strong pressure on the screwdriver can be after so many attempts to spoil Phillips that it would be impossible to turn the screw.

If the screw can not turn right, do the following:

- Take exactly matches the size of the screw solid strong screwdriver and try to hammer on the end of the handle screw driver to loosen the screw connection. Often heavily corroded screw in only the head, so after hitting a hammer can easily turn;

- If that does not work, use impact screwdriver. After each hammer blow on the back of the screwdriver handle shock occurs cranking its working parts. This tool allows you to turn almost any screw.
