ceramic coated self drilling screws

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.
