Installation

Installation

Installation

  • SDW screws install best with a low-speed drill and a T40 6-lobe bit (bit included with every box of screws)
  • Pre-drilling is typically not required
  • Drive the fastener so that the top of the head is slightly embedded into the top surface of the timber. To ensure correct performance, do not under or over-drive the fastener
  • Individual screw locations may be adjusted up to 75mm to avoid conflicts with other hardware or to avoid timber defects
