How to installation 

  1. Drill a hole in the base material, the hole should be drilled deeper than the screw embedment depth according to our ETA installation instruction (pilot hole required)
  2. Clean out the hole of all debris.
  3. Insert the pointed end of the concrete screw through the fixture and into the hole in the base material.
  4. Drive the screw or use powered impact wrench slowly, allowing the threads to tap into the base material.
