How to take out the broken Self-tapping screw:
1. For the Self-tapping screw broken in the wall or in the wood block, first use a Bench grinder to grind the broken part, prepare a small type of drill bit to drill first, then change it into a larger drill bit, wait until the broken part gradually falls off, and then change it into a thread to tap the tooth, so that the Self-tapping screw broken in the wall can be screwed out. In addition, an iron rod can be welded onto the broken surface and then twisted out in a counterclockwise direction.
2. If the Self-tapping screw is not too hard, first chisel the surface, make a small hole from the middle, drill with a drill bit, and then use a broken wire extractor in the vertical direction, and screw it out in the opposite direction.
3. If the Self-tapping screw has rusted, it cannot be taken out by the above methods. The Self-tapping screw can also be taken out through the principle of Thermal expansion. If it still cannot be removed, it is necessary to smash a relatively large hole, damage the wall or the substandard product, and repair it later.
What tools are needed to remove the screws:
1. Removing screws by hand takes a lot of time, so it requires the use of relevant tools. For example, you need to use a hammer, as well as a screwdriver or screwdriver. First, heat the local area and make a small hole on the broken surface. Insert a screwdriver into the small hole and then use a hammer to hammer it out bit by bit.
2. You can also use a hammer and chisel to work together, first making a small hole in the outer wall, then clip the chisel into this small hole and use the hammer to gradually break it out.
3. You can also use pliers, including welding nuts, to weld the nuts and broken bolts together, and turn the bolts with a wrench to remove the screws.
