Product Information：
Expansion Fixing Screw is a kind of Sanitary Accessory that uses the friction force generated by the expansion caused by the wedge inclination to achieve a fixed effect.
Expansion Fixing Screw is composed of screw and expansion pipe. From the material, it is divided into metal expansion nails and plastic expansion nails, from the installation method into screw-in expansion nails and percussion expansion nails.
Product Features:
The biggest difference between expansion bolts and a nail is: expansion bolts have expansion tubes, but anchor bolts do not.
Expansion bolt: After driving the expansion bolt into the hole on the ground or wall, use a wrench to tighten the nut on the expansion bolt. The bolt goes out, but the outer metal sleeve does not move. Therefore, the big end of the bolt is the metal sleeve. Expand the hole so that it fills the entire hole. At this time, the expansion bolt cannot be pulled out.
There are two installation methods for one nail: 1. One-time embedding method: when pouring concrete, embed the anchor bolts. 2. Reserved hole method: the equipment is in place, the holes are cleaned, the anchor bolts are placed in the holes, and the equipment is positioned and corrected, and then poured with non-shrinkage fine stone concrete one level higher than the original foundation, and tamped and compacted .
How to remove the expansion screw on the toilet lid:
You can first remove the screw cap on the toilet lid, and then use the screwdriver to knock the screw in. When the screw moves back and forth, you can slowly disassemble it. If it still doesn't work, find an expansion bolt sleeve of the same model to cover the screw, and knock the sleeve inwardly by yourself. At this time, the bolt sleeve can move inward and loosen. Generally, the expansion screw can be removed.
Should the bathroom cabinet be fixed to the wall with expansion screws, or glass glue?
No glass glue is required. Expansion screws for bathroom cabinets are inside, so they don’t soak in water when using them, so glueing has no practical meaning.
The surface materials of the bathroom cabinet can be divided into natural stone, artificial stone, fireproof board, baking varnish, glass, metal and solid wood, etc.; the base material is the main body of the bathroom cabinet, including particle board, fine mesh board, MDF, moisture-proof board, and oak board. , Red wood boards, etc., the substrate generally will not be blistered, not to mention the expansion screws inside, so there is no need to glue.
