Many users do not know the difference between high-strength nuts and general nuts. In fact, they can easily distinguish them by understanding their standards and other characteristics. The so-called high-strength nuts are special bolts with high strength and high fatigue resistance used in special equipment or projects. Of course, generally high-strength nuts are used with high-strength bolts to achieve better use.
The mechanical function of the nut mainly depends on the hardness of the nut, the height of the nut, and the wall thickness of the nut.
