Compatible with cover roof construction for slate roofs. Easily penetrates any hard roof and securely fastens!
It is often difficult for regular screws to penetrate or fit. This drill screw is ideal for the cabal roof method (a construction method where a metal roof is placed over a slate tile roof). By sharpening the tip, it can penetrate even hard slate that would typically cause the tip of a regular drill screw to chip. The head is a special bind head that securely holds the metal roof while ensuring good bit engagement. The screw section is a coarse screw that firmly grips the sheathing board. With a custom shape from the head of the screw to the tip, this drill screw makes the cabal roof method significantly easier.
