To properly configure an anchor wall drywall, you must drill a pilot hole first. It is an opening hole for the tip of the anchor penetrates smoothly into the drywall without drilling holes in their own way. Without a guide hole, the anchor wall would be introduced into the space by using a hammer, causing splits or gypsum possibly splitting.
