Installation

Using a 3/16 carbide masonry drill bit and hammer drill (in hammer mode), drill a hole 1/4" deeper than the minimum embedment requirements of the concrete screw to be installed*. Clean the dust from the hole using compressed air or hand pump. Use a 5/16" nut setter with hammer mode turned OFF or a standard rotary drill to install fastener until seated. Do not over torque as it can cause the head to snap or stripping of the recess.

*When installing into Hollow Block CMU drill through the full thickness of face wall.
