1.You'll need a small "percussion drill" to make holes in the concrete wall.
2."Expansion screws" are needed to nail the "basket board" to the wall. In other words, the "expansion screw" should be nailed into a "hole" that has been made in advance.
Note:1Measure the thickness of the wall. Confirm the material of the wall, is it cement or brick? If it's a brick, the expansion screw shouldn't be used.
2.The hole should be the same as the diameter of the "expansion screw" you bought.
What, I don't know how big screws to buy, and I don't have tools yet? )
Then you first find a "hardware store", tell the boss what you want to buy expansion screws for, tell him the thickness of the wall, the material.
The boss will basically tell you how big the screws you need to buy. (Don't buy it yet).
Then, you go to the labor market, and those who do odd jobs will have percussion drills in their hands.
Negotiate the price, let him help you analyze how big the screws need to buy. (It is estimated that you will have to ask for 50 yuan, and 30 should be capable).
What the shopkeeper and the worker said, the screw number, you compare it yourself. You know how big the screws you need to buy.
The most important thing is the material and screws of your wall, you can expand the screws at once. See what exactly suits you or not.
