To install the Power Screw Bolt , using the proper size carbide bit, drill a pilot hole at least one anchor diameter deeper than the desired anchor embedment. Blow out the concrete dust. Using an electric impact wrench, or socket wrench, insert the anchor into the hole and tighten the anchor until it's fully seated. If using an electric impact wrench, start on a light torque setting to prevent over-torqueing or damaging threads. If installing into concrete block, do not use an impact wrench. Use a socket wrench in this application.
