Because stainless steel and carbon steel have essential differences. Stainless steel has good ductility. If it is used improperly, it will easily lead to the unscrewing of the stainless steel screw nut. It is commonly called "locking" or "biting death". Therefore, you need to pay attention to the following points when using:
(1) The nut must be screwed perpendicular to the axis of the screw, not to tilt;
(2) During the tightening process, the force must be uniform and the force should not exceed the safe torque; (with the safety torque meter)
(3) Use a force wrench or a socket wrench as much as possible to avoid using an adjustable wrench or an electric wrench;
(4) It must be cooled when it is used in high temperature, and should not be rotated quickly during use, so as to avoid sudden rise in temperature and lock up;
