Deep thread, standard length, even pitch Easy to install, usually used in heavy-duty installations |
The expansion bolt has a length of a component such as a screw and an expansion tube, and the tail of the screw is conical. The inner diameter of the cone is larger than the inner diameter of the expansion tube. When the nut is tightened, the screw moves outward, and the conical portion is moved by the axial movement of the thread to expand. The outer peripheral surface of the tube forms a large positive pressure, and the angle of the cone is small, so that the wall expansion tube and the cone form a friction self-locking, thereby achieving a fixed function. |
The carbon steel Q235 high-quality material is used at the tail, and the hole diameter of the durable and perforated hole matches the tail. |
