Hex Head Self Drilling Screw

These are self – drilling screws for color steel tiles. They belong to the category of self – tapping screws. Usually, their heads come in different shapes such as hexagonal and cross – recessed. The tail of the screw rod is sharp with threads, and some have a sealing washer under the head, which can enhance the waterproof performance. They are mostly made of carbon steel with galvanized treatment or stainless steel, providing good rust – prevention and corrosion – resistance capabilities.

They are mainly used for the installation and fixation of color steel tile roofs and walls. They can directly drill into and screw into metal sheets like color steel plates. Additionally, they are also applicable to the connection of light – gauge steel keels and other related building structures.

First, determine the installation position on the color steel tile or relevant metal material. Then, use a suitable power tool (such as a cordless drill) equipped with a bit that matches the screw head type. Align the screw with the pre – determined position, start the power tool, and slowly drive the screw into the material. The self – drilling tip will penetrate the material while the threads gradually embed, achieving a firm fixation.
