High strength bolts can withstand a greater load than ordinary bolts of the same specification. In addition to their high material strength, high strength bolts apply a large preload to the bolts, qui est une force de serrage entre les éléments de connexion, ce qui le rend perpendiculaire à la vis Il y a beaucoup de frottements dans le sens, et la précharge, anti-slip coefficient and steel type directly affect the bearing capacity of high strength bolts.
