GOK, GOK-N, GOK-PLUS-N + WX, WX-T Roofing fixing system

Pre-assembled telescopic fastening system for trapezoid sheet substrate,  max thickness of 2x1.25mm

Features and benefits

  • Impact-resistant material used ensures constant mechanical properties over the lifetime of a roof. Also, retains its properties over a wide temperature range. 

  • The cone’s optimal shape facilitates speed and ease of installation through the thermal insulation.
  • Internal sleeve design allows pre-assembly with any Rawlplug roofing screw, shortening installation.

  • Hardened screw's thread surface. High quality anti-corrosion coating guarantees resistance of 15 Kesternich cycles.
  • The shape and type of screw's 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.
