The "Straight Slate Tile Renovation Screw Circle Head" is a drill screw (Pairovis) that can penetrate up to 4 slate tiles. The screw at the top of the drill tip increases driving power, allowing for one-shot penetration through metal roofs, slate tiles, and underlying wooden materials without the need for pilot holes. The unthreaded section prevents the metal roof from lifting, and also prevents lifting and cracking of existing slate tiles. In the case of 1 to 2 slate tiles, it effectively prevents lifting. 【Features】 ■ The unthreaded section prevents the metal roof from lifting and also prevents lifting and cracking of existing slate tiles; it effectively prevents lifting in the case of 1 to 2 slate tiles. ■ The screw at the top of the drill tip increases driving power. ■ Allows for one-shot penetration through metal roofs, slate tiles, and underlying wooden materials without the need for pilot holes. ■ Can penetrate up to 4 slate tiles. *For more details, please refer to the PDF document or feel free to contact us.

The screw product "Sharaku" maintains its water-stopping effect even when driven at an angle. The spherical part below the head closely adheres to the entire circumference of the counterpart hole (washer), allowing for the maintenance of the water-stopping effect. Since the entire spherical part can uniformly apply pressure to the counterpart hole (washer), the sealing effect with the packing is enhanced. It can accommodate a maximum tilt angle of up to 15°. Depending on the application, it can be shaped to the "Hirata standard" tip. With the adoption of a special cutting edge (high-catch tip), it can easily penetrate even at the knots of rafters. Even with four layers of colonial, it can penetrate sufficiently. By shaving with the special cutting edge, it becomes less likely to cause wood splitting or cracking in the colonial.

As a background to the current construction, with the evolution of tightening tools, high rotation and high torque have become possible, leading to a reduction in work time. However, this has also resulted in a greater burden on screws, and issues such as head stripping or screw spinning have become more common. With current tightening tools, it is quite difficult for the operator to maintain a fixed position while tightening, as the fastening force reaches its peak instantaneously. In response to this era of construction difficulties, we have developed a product that can cover these issues with screws. *For more details, please download the catalog or feel free to contact us.*

**Points for Slate Roof Tile Renovation Construction** In the case of new construction using only conventional slate tiles, there are pre-drilled holes for nailing, which are utilized during installation. However, when installing a metal roof over slate tiles, it is necessary to drill holes in the slate tiles and ensure they are securely anchored to the wooden roofing substrate. Therefore, we have developed an efficient original screw that can be installed without pre-drilling holes, even in hard slate tiles. *For more details, please download the catalog or feel free to contact us.*

"Fasteners for structural components" are screws used to secure metal roofing steel plates (structural components). By adopting a special tip design, they can be installed without pre-drilling into thin steel plates or underlying wooden materials, preventing the phenomenon of separation between steel plates. Additionally, we have a wide variety of head colors that match the color of the steel plates in stock. They are widely used in many metal roofing materials due to their workability, aesthetic appeal, and waterproofing properties. 【Features】 By adopting a special tip shape... ○ It is possible to penetrate without pre-drilling for thin steel plates + thin steel plates + underlying wooden materials. ○ It effectively draws together thin steel plates, preventing separation. ○ These screws excel in workability and durability. ○ We offer a color variation of 8 colors to match the color of the counterpart steel plates. *For more details, please download the catalog or feel free to contact us.
