LONG INNER CAP NUT, RH GR - STEEL WHEEL
Lug Nuts: Lug nuts screw onto the wheel studs and secure the wheel onto the hub of a truck or trailer. Always important to tighten lug nuts down evenly in a star pattern to keep the wheel straight and prevent overtightening of one lug nut compared to the rest of them.
