Concrete Anchor 1/8 inch - 4 Pack.
This Concrete Anchor is meant for holding ladder racks or back boards to concrete or brick walls. To install the anchor first drill a hole into the concrete surface with a carbide tip drill bit and a hammer drill. The hole must be ¼ of an inch deeper than the anchor bolt will reach and it’s recommended to drill at least 1.5” deep. After the hole is drilled out clean out any debris left behind and drive the anchor in with a hammer until the washer is flush with the surface. Finally, tighten the hex nut on the bolt until 14 ft. lbs. of torque is reached.
