1. During the use of the weld nut, if the assembly torque is too large, the force will be uneven. When the yield limit of the weld nut is exceeded, deformation will occur. If the continuous impact load is The weld nut was broken due to excessive elongation. So in life what we think the closer the better is unscientific.
2. In addition, do not sloppyly install the welding nut by mistake or install it indiscriminately when overhauling the length of the welding nut, otherwise it will cause the inaccurate positioning of the saw teeth, and it is likely to cause the welding nut to break. It is also possible that the weld nut is broken due to material problems, processing defects or processing techniques.
