I believe that everyone will encounter the door lock in life, sometimes it is necessary to replace it, the door lock screws is slippery or the screws hole is moving. What should I do?

1. Screw holes can be injected into the screws hole with a small amount of 5O2 glue, then screws the screws, then remove the screws and turn the screws with the tip pliers (only the screwsdriver is afraid again to lead the screws tooth), wait It is necessary to completely harden the glue;

2. Screw holes, and then tap with a tap. Less spending less, the skill is high.

Then the screws head is rushed, how can we take it out?
1. Troubled the screws, we want to make a cross-shaped or word-type shape in a circular use, simply a word, and take a depth, then take out with a word screws.

2. Use a small drill bit to punch the screwsed screws, then screws in with a refilateral tap, form a screws in it, if the refilateral teeth, then use the corresponding small screws to screws it in.

3. Alternatively, the solder is heated with the solder iron, dripped on the screws and screwsdriver, so that they cool the solidification, and then screws it smoothly, but this method is more cost-effective.

4. If the screws is already out, then this is good, we can use the sharp pliers or tiger clamps in diameter to hold force, then rotate the pliers, there is a heating method, we can heat the screwsdriver , Then top on the screwsed screws, wait a few seconds, then rotate, so that the screws is slightly softened to the cross or a typique, if you have a way to heat the screws.
