NASCAR fined crew chief Rodney Childers $10,000 for a safety violation after the Monster Energy NASCAR Cup Series’ Coca-Cola 600 last weekend at Charlotte Motor Speedway.

The No. 4 Stewart-Haas Racing Ford driven by Kevin Harvick was found to have one lug nut improperly installed in post-race inspection.

Harvick started the Memorial Day weekend race in the Coors Light Pole position but finished in eighth place. He sits fourth in the driver point standings this season.
