When removing the hexagon socket head screw and the phenomenon of sliding teeth, there are generally the following three methods to help remove the hexagon socket head screw.

1. Use an alloy drill that is one size smaller than the screw to be removed, and drill the screw to be removed directly. After that, there will be some iron filings left around, which can be cleaned up slowly. 2. It can be treated by EDM. If the workpiece is not easy to move, there is a portable EDM machine that you can look for. (After removing the screw in this way, the original internal thread hole is likely to be damaged)

After the hexagon socket head screw is taken out, if the thread is slightly damaged, you can re-tap it with a thread tap, and it can be used normally; if the thread is seriously damaged, it needs to be repaired with a thread sheath, which not only forms a new It can also protect the internal hexagon screw thread.
