Home > Companies > Fixfast Ltd > DrillFast® Fasteners for Timber to Steel 1.2–3 mm Thick

Carbon steel self-drilling fasteners for roofing and cladding (1.2–3 mm).

Features and benefits:

  • High quality carbon steel with SAE1022 hardened case.
  • Good drilling and tapping performance.
  • Wings behind the drillpoint will form clearance holes through the timber, and will break off in contact with the substrate.
  • Consistently high pull-out and shear performance.
  • Manufactured in accordance with ISO 9001 and ISO 14001 Quality and Management Systems.

Applications:

For mechanically fixing timber components to light metal purlins and rails. For use in the following locations:

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

To be fixed with 2-PZD or TX30, dependent on fastener chosen.
