How to install wooden boards by slotting on the wall

First, drill holes on both sides of the board, then drill two holes on the wall with an electric hammer, then screw the expansion screw into the hole, and fix the thin iron wire on the expansion screw through the holes on both sides of the board.

What is an expansion screw?

Generally speaking, the expansion screw is a metal expansion screw, and the fixation of the expansion screw is achieved by using the wedge-shaped inclined plane to promote expansion and generate friction grip force. One end of the screw is threaded and the other end is tapered. The bread outside is made of iron (some steel pipes), and half of the iron cylinder (steel pipes) has several cuts. Put them together in the hole punched in the wall, then lock the nut. The nut pulls the screw out and pulls the awl into the tin tube. The tin tube is expanded, so it is tightly fixed to the wall. Generally used for fastening fences, awnings, air conditioners and other materials on cement and bricks. However, its fixation is not very reliable, and the load vibration may loosen, so it is not recommended to install ceiling fans. Expansion screws are widely used in various decoration occasions because of their small drilling, large tension, flat and exposed after use, and easy disassembly when not in use, which has obvious advantages in keeping the wall flat.
