Roller short description:

Excavator bolts and nuts  generally use common thread, whose thread rise Angle is less than the equivalent friction Angle of thread pair, in order to meet the self-locking condition of thread pair. After the bolt is tightened, the friction between the bolt head and the nut support surface can also prevent loosening.
