Stainless steel screws will break.What if the stainless steel screws are damaged?Why are stainless steel screws magnetic?Let’s take a look at the solution to the fracture of stainless steel screws and the magnetic cause.I hope it’s helpful to you.

So what is the reason for the fracture of stainless steel screws?

1. Quality of screws

2, the strength of the screw

3. Pre-tightening torque of screws

4, the fatigue strength of the screw screw material is not qualified, heat treatment is not qualified, the product manufacturing process is not qualified, the stainless steel screw is not reasonable, the use of the environment is bad and so on have a direct impact.In the case of these prerequisites are standard, the majority of stainless steel screw fracture is because of loosening and fracture.

What if the stainless steel screws are damaged?

1. Remove the dirt from the surface of the damaged screw first, then smash the center of the part with the center screw.A drill with a diameter of 6-8 mm is then drilled in the center of this section.Please note that the hole must be punched through.After drilling, the small bit was removed and replaced with a 16 mm diameter bit, and the hole of the breakbolt was continuously enlarged and drilled through.

2. Take an electrode with a diameter of 3.2mm or smaller, and break half of the full length of the bolt from the inside of the broken bolt to the outside with a small current.The starting arc should not be too long.To avoid burning the outer wall of the damaged bolt.After welding to the upper end of the broken bolt, continue to weld the cylinder 14-16 mm in diameter and 8-10 mm in height.

3. After surfacing, hit the end face with a hammer to make the broken bolt vibrate along its axial direction.The heat generated by the arc and the subsequent cooling and vibration at this time will cause bolts and valve body threads.There was some slack between them.

4. Careful observation When a bit of rust is found to leak through the crack after tapping, the M18 nut can be placed on the surface stud and welded together.

5. After welding, cool down slightly, heat the nut with a plum wrench, twist it back and forth, or twist it back and forth with a small hand hammer, beat the end of the nut, so that the broken stainless steel bolt can be tightened.Take away.

6. After removing the damaged bolts, use the appropriate wire hammer to thread on the rack to remove rust and other debris.
