Description

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.
