How can I securely mount a heavy mirror on a stud in the wall?

To securely mount a heavy mirror on a stud in the wall, use a heavy-duty mirror mounting kit that includes appropriate screws and anchors. Locate the stud using a stud finder, then mark the position on the wall. Drill pilot holes into the stud and attach the mirror mounting hardware using the provided screws. Make sure the mirror is level and secure before hanging it on the wall.
