R-WB Self-drilling screws for steel

Double-threaded screw for trapezoidal steel sheet – max thickness of 2 x 1.25mm

Features and benefits

  • Hardened thread surface
  • High quality anti-corrosion coating guarantees resistance of 15 Kesternich cycles.
  • The shape and type of thread is designed specifically for connecting to metal sheets
  • The drill point is designed to provide a fast and hassle-free installation. Sharp point of the drill prevents movement of the surface of the fixture.
  • Reduced drilling point ensures optimal tightness and correct hole diameter in thin metal sheets.
  • Two types of threads: one designed for mounting into construction, second under head thread, prevents external panel dents and helps to seal the connection
