Easy Installation Guide Drill Pre-Hole Use the matching drill bit to create a pilot hole. Make sure the hole depth is 0.5 inches deeper than the screw’s embedded length, and keep the embedded range between 1 inch and 1-3/4 inches for ideal mounting results. Fasten the Screws Insert the concrete screw straight into the pre-drilled hole and drive it in steadily. Tip: Avoid over-tightening, as too much force may break the screw head or damage internal threads. Finish Installation The whole mounting process is quick and hassle-free. These screws can also be easily removed whenever necessary.
