Expansion hooks are usually composed of expansion bolts and hooks. It is fixed to the wall by expansion bolts, and uses the friction between the bolt expansion and the wall to tighten and fix the water heater. When installing, first drill a hole on the wall, then insert the expansion bolt into the hole and tighten the nut. The bolt will move outward, and the sleeve will expand and tightly press against the wall, thus fixing it. According to the weight of the object and the installation environment, different specifications and models of expansion hooks can be selected. Common models include M6, M8, M10, etc., and their load-bearing capacity varies on different substrates.
Installation precautions:
1. Choose the appropriate expansion hook specification.
2. Ensure the wall is firm: Before installation, check whether the wall is flat and firm, and avoid installing on hollow walls or soft walls.
3. Correct installation: Use an impact drill or electric hammer to drill holes, ensuring that the hole diameter matches the bolt. When tightening the nut, pay attention to the force to avoid over tightening or over loosening.
4‌. Regular inspection: After installation, regularly check the connection status to ensure safety and reliability.
