As an important part in the construction industry, full threading plays a key role. In the past fifty years, fasteners have been widely used in the construction industry and some mechanical equipment. Due to the general improvement in the efficiency and strength of building materials, the body weight of buildings is developing in a lighter direction, and the ratio of strength to weight of its constituent materials is also increasing. A building that is too light is not a good thing, its resistance to wind and impact is gradually weakened, so there is a safety hazard when we use these buildings. In the past time, some people thought that a building could be built only by relying on the weight of the building itself and the adhesion of mortar, but this is not the case, any building is not built only by mortar, this time all Mechanical fasteners such as buttons play its role. In order to make up for the structural defects caused by the weight reduction. As the weight of building components becomes lighter, their volume is also reduced, so that the place where the full thread is installed is correspondingly reduced. It is for this reason that the strength of the full thread is required to be increased, and its performance It must be completely predictable, so as to ensure the safety of the building, and also improve the wind resistance and impact resistance of the building. Don’t underestimate the effect of full threading, which sometimes plays a major role.
