After some major issues with inspection difficulties by over a dozen teams prior to qualifying for the Auto Club 400 at Fontana last weekend, the penalties issued by NASCAR after post race inspection were very light.

The lug nut monster took issue with the number 18 over the weekend in the last stop on the west coast swing.

In the Monster Energy Cup Series, the Joe Gibbs Racing number 18 driven by Kyle Busch was charged with not having all 20 of his lug nuts properly secured in post race inspection. As a result of the infraction, Busch’s crew chief Adam Stevens was fined $10,000 with no further punishment issued.

The Xfinity Series number 18, also owned by Joe Gibbs Racing, driven by Ryan Preece in the Monster Energy debut was also charged with not having all of his lug nuts properly secured in post race inspection. As a result, crew chief Eric Phillips has been fined $5,000.
