expansion bolts for hollow structural steel sections

The installation process of an M12 chemical anchor involves drilling a hole into the substrate to the appropriate depth, then filling it with a specially formulated two-part resin. The anchor bolt is then inserted into the resin while it's still pliable, and as the resin cures, it forms a tight grip around the bolt, creating a robust connection. The curing time varies depending on the specific chemical composition of the resin, ambient temperature, and humidity.

These screws feature a wide, flat head, which distributes the pressure evenly, preventing the board from splitting. The sharp point enables easy penetration into the material without pre-drilling, saving time and effort The sharp point enables easy penetration into the material without pre-drilling, saving time and effort The sharp point enables easy penetration into the material without pre-drilling, saving time and effort The sharp point enables easy penetration into the material without pre-drilling, saving time and effort35mm chipboard screws. Additionally, they often have a coating, such as zinc plating, to resist corrosion and enhance their longevity.
