1. During the use of the welding nut, if the assembly tightening torque is too large, the force will be uneven. When the yield limit of the welding nut is exceeded, deformation will occur. Weld nut breaks due to excessive elongation. So in life we think that the closer the better is unscientific.
2. In addition, when overhauling the length of the welding nut, do not install it carelessly or randomly, otherwise, the positioning of the sawtooth will be inaccurate, which may cause the welding nut to break. It is also possible that the weld nut has broken due to material problems, machining defects, or processing techniques.
