SELF-DRILLING SCREW FOR CORRUGATED METAL SHEETS AND STEEL WITH WATERTIGHT SEALING SAR
Self-tapping screws for steel and screws for corrugated metal sheets
SAR screws for sheet metal are specifically designed for the direct fastening, without pre-drilling, of metalwork elements and sheet metal onto steel substructures up to 6.0 mm thick. They are a proven solution for metal roofing applications, both in large industrial buildings and in smaller projects such as garages and outbuildings.
The SAR self-drilling screw features a self-drilling tip with chip-evacuation design, ensuring excellent drilling capacity in steel up to 6 mm thick, combined with an aggressive self-tapping screw thread specifically designed for steel. The hex head with integrated SW 10 washer ensures uniform load distribution across the contact surface.
Thanks to its high steel drilling capacity and the watertight sealing provided by the integrated washer, it is particularly suitable for application on corrugated metal sheet, ensuring fast installation and long-term reliability.
Technical characteristics of hex head self-drilling screws for steel
SAR self-drilling screws for corrugated metal sheet are manufactured from electro-galvanised carbon steel, ensuring durability and corrosion resistance in exposed environments.
The integrated washer with EPDM seal ensures watertight fastening, a critical requirement for metal roofing applications exposed to weathering.
The self-drilling tip optimised for chip evacuation is a key design feature: it allows direct drilling into steel without pre-drilling, significantly reducing installation time and minimising the margin for error on site. The hex head with integrated SW 10 washer allows easy use with standard tools, improving ergonomics and installation speed.
SAR screws with sealing washer perform effectively in atmospheric corrosivity classes C1 and C2. The ability to fasten directly onto metal substrates, combined with the watertight EPDM washer, makes these screws for metal sheet the ideal solution for corrugated metal roofing in residential, commercial and industrial applications.
Which self-drilling screw for watertight sealing on corrugated metal sheet?
The SAR self-drilling screw is the correct choice for corrugated metal sheet thanks to the combination of a high-performance drilling tip (up to 6 mm in steel) and an integrated EPDM washer ensuring long-lasting watertight sealing. This solution eliminates the need for pre-drilling and ensures durable sealing over time.
