How to remove broken screws?

2018-05-12 08:00:11

This paper introduces a method of taking out the remaining part of a broken screw.

Tools/Materials

Bricks, cones, hand drills

Methods/Steps
1

1. When we screw out the screw, we often do not pay attention or too much force, and the screw head is broken.

2

2. To remove the remaining part of the screw that is broken inside, first make a positioning hole with the positioning pin.

3

3. Then it's time to drill. Choose a model smaller than the original bolt, to avoid drilling the inside of the external thread drilling.

4

4. The tap used is required to rotate left direction. Note: The right hand tap is rotated in the direction of the bolt inside, and the wrong direction will break the bolt.
