Get a drilling machine to drill the wall hooks into the wall. Find a drill bit that matches the size of the expansion tube provided. Drill a hole into the wall and push the expansion tube gently using a hammer. Remove any excess expansion tube protruding out of the wall for a smooth finish. Next, place the wall hooks on the wall and push the screws inside. Use a hammer or a screwdriver to further push the screws inside the wall for a firm hold.
