The self-tapping screws are equipped with a special coating that does not flake or damage when screwed. This makes the drilling screws extremely resistant to mechanical damage and UV radiation during installation and retain their appearance in the long term.
• Hexagonal design and easy installation: the hexagonal head of the screws with seal prevents slipping and allows high torque. The trapezoidal sheet metal screws require no pre-drilling. The self-tapping screws can be easily and efficiently mounted with a wrench or power tool.
• Self-drilling and self-sealing: the sheet metal screws with seal easily penetrate metal sheets. The screws for roof sheet are equipped with EPDM sealing rings that effectively prevent moisture from entering, compensate for temperature expansions and ensure a durable, weather-resistant connection. The self-tapping metal screws are suitable for roof sheet screws with sealing rings.
