POWER-Skru Bolt Anchors
Installation
Step-By-Step
Installation in Concrete
  1. Using the proper size carbide bit, drill a pilot hole at least one anchor diameter deeper than the desired anchor embedment.
  2. Blow out concrete dust.
  3. Using an electric impact wrench, or socket wrench, insert anchor into hole and tighten anchor until fully seated. If using an electric impact wrench, start on light torque setting to prevent over torturing or damaging threads.
    NOTE: Always wear safety glasses.

Installation in Concrete Block (CMU)
NOTE: Do not use an impact wrench for installation into CMU walls.
  1. Using the proper size carbide bit, drill a pilot hole at least one anchor diameter deeper than the desired anchor embedment.
  2. Blow out concrete dust.
  3. Using a socket wrench insert anchor into hole and hand tighten anchor until fully seated.
    NOTE: Always wear safety glasses.

*To assure full load values, do not ream the hole or allow the drill bit to wobble. Use solid carbide-tipped drill bits meeting ANSI B212.15 diameter standards.
