Six crew chiefs across both the Cup and Xfinity Series have been fined for lug nut violations coming out of last weekend’s racing at Atlanta Motor Speedway.
Each crew chief’s respective entry had one lug nut found not safe and secure in post-race inspection.
Cup crew chiefs Adam Stevens (No. 20 – driver Christopher Bell), Jonathan Hassler (No. 21 – driver Matt DiBenedetto), Mike Wheeler (No. 23 – driver Bubba Wallace), and Greg Ives (No. 48 – driver Alex Bowman) were fined $10,000 each by NASCAR.
No penalties were issued coming out of Friday’s NASCAR Camping World Truck Series race at Knoxville (Iowa) Raceway.
