lugnuts

Secure the tires

Lugnuts are the heavy nuts that secure a wheel to a vehicle's axle, tightened onto threaded bolts called lug studs.

Changing a tire means loosening the lugnuts, swapping the wheel, then tightening them again in a star pattern: I can't get these lugnuts off—they're rusted solid.

Sometimes spelled as two words.
