When the bolt is tightened, it will expand. There is a big head at the end of the bolt, a round pipe with a diameter slightly larger than the bolt is sleeved outside the bolt, and there are several openings at the end. When the bolt is tightened, the tail of the big head will be brought into the open pipe, and the pipe will be enlarged to achieve the purpose of expansion, and then the bolt will be fixed on the ground or wall to achieve the purpose of rooting.
The principle of expansion bolt is to drive the expansion bolt into the hole on the ground or wall, and then use a wrench to tighten the nut on the expansion bolt. The bolt moves outward while the metal sleeve outside does not move. Therefore, the big head under the bolt expands the metal sleeve to make it full of the hole.
