  • Grade 1.4301 (304), A2 stainless steel is used for optimum resistance to corrosion.
  • Bi-metal, manufactured for superior drilling performance.
  • Good pull-out and shear performance.
  • High thread provides optimal clamping force to the top sheet.
  • Manufactured in accordance with ISO 9001 and ISO 14001 Quality and Management Systems.

Applications:

Suitable for the mechanical fixing of composite panel systems to light metal purlins and rails, and timber. For use in the following locations:

  • Buildings in residential and commercial settings with humidity class of Class 1, Class 2, Class 3 or Class 4 to BS 5250.
  • Buildings with an internal temperature range of -45°C to 50°C.
  • Coastal locations.

To be fixed with Fixfast GreenDrive (8 mm hexagon integral socket with retaining clip).
