Product Parameters
The commonly used expansion bolt in door and window installation is a screw that uses thread movement to open the expansion piece and generate compression force to achieve a fixed effect. Expansion bolts are widely used in the installation process of doors and windows because they can provide sufficient support and stability, ensuring that the windows will not loosen or shift when subjected to external forces such as glass weight and wind pressure.
The installation method of expansion bolts usually includes the following steps: first, select an alloy drill bit with the same diameter as the expansion bolt tightening ring, and then drill holes in the wall, the depth of which should match the length of the bolt. During installation, it is necessary to place the expansion bolt kit together into the hole and be careful not to unscrew the nut to prevent the bolt from falling into the hole and being difficult to remove. Next, tighten the nut to expand and secure the expansion tube in the wall, and finally install the door and window frames and other fixing components onto the bolts.
When selecting expansion bolts, the appropriate specifications and types should be chosen based on the wall material and required bearing capacity. For example, metal expansion bolts are suitable for structures such as reinforced concrete and lightweight bricks. In addition, there are various types of expansion bolts, including plastic expansion, metal expansion, stainless steel expansion, etc. Different types of expansion bolts are suitable for different installation scenarios.
In short, the reasonable use of expansion bolts in door and window installation can ensure the firmness and safety of doors and windows, while also effectively preventing water leakage and structural damage.
