lug bolt
Secures car wheels
A lug bolt is a fastener that secures a wheel to a vehicle's hub, threading directly into the hub rather than onto a separate stud.
Common on European cars, lug bolts differ from lug nuts, which thread onto permanently mounted studs.
I stripped one of the lug bolts changing the tire.
