How to use plastic expansion screws
Plastic expansion screws are a common fastener and are widely used in home decoration, electrical appliance installation and other fields. It is simple to use, but requires attention to some details to ensure firmness and safety. This article will introduce in detail the use of plastic expansion screws, and provide you with a practical guide based on hot topics and hot content on the Internet in the past 10 days.
1. The composition and principle of plastic expansion screws

Plastic expansion screws are mainly composed of plastic expansion tubes and metal screws. Its working principle is that the expansion tube expands in the hole through the rotation of the screw, thereby generating friction and achieving a fixed effect.
| components | Material | effect |
|---|---|---|
| plastic expansion tube | Nylon or polyethylene | Expands in the hole and generates friction |
| metal screws | Stainless steel or carbon steel | Expansion of the expansion tube driven by rotation |
2. How to use plastic expansion screws
1.Choose the right expansion screw: Select appropriate expansion screw specifications based on the weight of the installation object and the material of the wall.
2.drilling: Use an electric drill to drill holes in the wall. The diameter of the hole should match the outer diameter of the expansion tube, and the depth should be slightly longer than the length of the expansion tube.
3.Clean holes: After drilling, use a brush or blower to clean away dust and debris in the hole to ensure that the expansion tube can be fully inserted.
4.Insert expansion tube: Gently tap the expansion tube into the hole, making sure it is flush with the wall.
5.Screw in the screws: Screw the screw into the expansion tube until the screw head is tight against the installation object.

|---|---|
| drilling | The hole diameter matches the expansion tube and the depth is slightly longer |
| Clean holes | Make sure the hole is free of dust and debris |
| Insert expansion tube | The expansion tube is flush with the wall |
| Screw in the screws | The screw head is tight against the mounting object |
