The high-strength bolt is broken, do you know how to remove it? Let's follow the Cheapest SS M6 L Bolt Wholesale Price editor to briefly understand it!
1. First remove the sludge on the surface of the broken head of the high-strength bolt, use the center gun to kill the center of the section, then use an electric drill to install a drill bit with a diameter of 6-8 mm, and drill the hole at the center of the section. To drill through. After the hole is drilled through, remove the small drill bit, replace it with a drill bit with a diameter of 16 mm, and continue to expand and drill through the hole of the broken bolt.
2. Take a welding rod with a diameter of less than 3.2 mm, and use a medium and small current in the drilled hole of the broken bolt to carry out surfacing welding from the inside to the outside. Take half of the entire length of the broken bolt at the beginning of the surfacing welding. When starting surfacing welding, the arc should not be too long to avoid burning through the outer wall of the broken bolt. After surfacing to the upper end face of the broken bolt, continue surfacing to form a cylinder with a diameter of 14-16 mm and a height of 8-10 mm.

3. After the surfacing is completed, hammer the end face with a hand hammer to make the broken bolt vibrate along its axial direction. Due to the heat generated by the previous arc and the subsequent cooling, coupled with the vibration at this time, the loosening between the broken bolt and the thread of the body will occur.
4. Carefully observe the high-strength bolts. When it is found that a small amount of rust leaks from the fracture after the knock, take the M18 nut sleeve, put it on the surfacing stud and weld the two together.
5. After welding, use a torx wrench while it is cool and hot, twist it back and forth on the nut, or tap the end face of the nut with a small hand hammer while twisting back and forth, so that the broken bolt can be taken out.
6. After taking out the broken bolt, use a suitable screw hammer to process the screw thread in the frame to remove rust and other debris in the hole.
