- Commodity name： Expansion Bolts
- Description
-
Expansion bolt is a commonly used fastener in construction and decoration, mainly used to fix objects on hard materials such as concrete or bricks. Its working principle is to expand the expanding part through the rotation of the bolt, thereby firmly fixing it in the substrate.
The main components of expansion bolts usually include:
1. Bolt: used to provide fixing force.
2. Expansion sleeve: usually a metal sleeve that expands as the bolt is tightened, increasing friction with the substrate.
3. Gasket: Used to increase contact area and disperse pressure.
4. Locking device: Some expansion bolts are designed with locking devices to prevent loosening caused by vibration or other factors.
When using expansion bolts, the following points should be noted:
- Choose the appropriate model: Select the appropriate expansion bolt based on the load-bearing requirements and substrate type.
-Drilling: Prior to installation, it is necessary to drill holes on the substrate with a diameter and depth that meet the specifications of the bolt.
-Installation method: Ensure correct installation according to the instructions to avoid loose fixation caused by improper installation.
Expansion bolts are widely used in fields such as furniture fixation, equipment installation, and building reinforcement.
