How to use

1. Apply lubricant to gaps between broken bolts, etc. and female threads.

2.Drill the drill blade provided in the center of a broken bolt or stuck bolt

3. Apply a small amount of mechanical oil to the opened hole and screw the corresponding extractor into the left turn (counterclockw).

4. After the extractor cannot be tightened, please be careful not to break carefully, and if you turn it counterclockwise direction, broken screws, etc. will loosen and fall out from the female thread, so it may be completely removed.

5. Extracted bolts are scapped with pliers or vice, and screw the extractor into the clockwise direction.

If the difference between the screw size and the drill hole is small, the thickness of the broken screws becomes thinner, so the extractor may expand the screw and make it difficult to unplug. Please note:
