1. How to use: When using, you must first use an impact drill (hammer) to drill a hole of the corresponding size on the fixed body, then install the bolt and expansion tube into the hole, and tighten the nut to expand the bolt, expansion tube, mounting part and fixed body into one.
After tightening, it will expand. There is a big head at the end of the bolt, and a round tube slightly larger than the bolt diameter is placed outside the bolt. There are several openings at the end. When the bolt is tightened, the tail of the big head is brought into the open tube, expanding the tube to achieve the purpose of expansion, and then fix the bolt to the ground.
2. Principle of use: The principle of expansion bolts is to drive the expansion bolts into the holes on the ground or wall, and then tighten the nuts on the expansion bolts with a wrench. The bolts move outward, but the metal sleeves outside do not move. Therefore, the big head under the bolts expands the metal sleeves to fill the entire hole. At this time, the expansion bolts cannot be pulled out. (However, its fixation is not very reliable. If there is a large vibration under the load, it may loosen. Therefore, it is not recommended to install ceiling fans and other items with large shaking amplitudes.)
