Hollow wall anchor bolts, also known as hollow wall anchors or hollow expansion screws, are mainly used in hollow walls, gypsum boards, fiberboards, plastic boards, wooden boards and other walls. They are light load anchor bolts. The heads and nuts at both ends are of two types: “welded” and “integrated”. They can be directly installed with an electric screwdriver or pulled with special tools.
Installation method:
1. The teeth on the head of the casing can be embedded in the hollow substrate, which can effectively prevent the casing from rotating in the hole during installation.
2. After installation, the expansion arm is opened behind the hollow substrate to form a large radius and large area of contact, providing a reliable
anchoring effect.
3. The matching screws can be easily removed, and the mounting parts can be repeatedly disassembled and assembled without affecting the anchoring effect.
4. Ordinary flat-blade or cross screwdrivers can be used for installation. If special installation tools are used, it can be more suitable for large-scale professional use occasions.

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.)
