  1. Drill the hole equal to the nominal diameter of the anchor. To assure full holding power, do not ream the hole or allow the drill to wobble.
  2. Drill the hole deeper than the intended embedment, but not closer than two diameters to the bottom (opposite) surface of the concrete.
  3. Clean the hole with a nylon brush and compressed air.
  4. Insert anchor into the hole.
  5. Using setting tool, drive expander shield over cone.
  6. Position fixture, insert fastener and tighten.

NOTE: Always wear safety glasses. Follow drill manufacturer's instructions. Use only solid carbide-tipped drill bits meeting ANSI B212.15 diameter standards.
