We just got done hanging 5 lock-ons on 2 properties a couple of weeks ago. We got the drill bit that's SUPPOSED to help...that was a waste of money. If you're going in a hardwood I would suggest drilling a small pilot hole. DO NOT DRILL A HOLE THAT'S THE SAME SIZE AS THE STEP. That would be very dangerous. Use a small drill bit to get you started. That made a world of difference.
