The contact point is a shiny spot surrounded by rust, directly above the screw hole for the bumper cover.
Lower engine cover off the car, with the screw in place.
Up close, you can see the tip worn flat.
Using a shorter screw would have been the easy way out, but I couldn't cope with the thought that someday a stock screw would be put back in. I cut the corner off the bracket with a Dremel.
