Chromed nut

A chromed nut for alloy wheels is a fastener that secures the wheel to the hub. The product gets its name from its chrome plating.

This surface treatment is responsible for the wheels’ appearance, and also provides protection against corrosion and aggressive external effects.

Product features

When choosing nuts for alloy wheels, the car make for which the fasteners are selected is the primary consideration. It determines the product’s characteristics:

• nut height and length;
• thread diameter, type and size;

Important: the minimum number of thread turns of engagement for alloy wheel nuts is 7-9; installing shorter elements (less than 10 mm long or 6 turns) negatively affects mounting reliability.

• nut seat is divided by type into spherical, flat and conical;

Important: when choosing a fastener with a spherical seat, closed-type nuts should be preferred, as this prevents dirt from getting inside the wheel structure.

• property class.

Application, mounting and use rules

A special wrench is used to mount nuts with a standard hexagon base. Depending on the design and model, 4 to 8 nuts are installed per alloy wheel. The optimal clamping force must be maintained to ensure reliable operation of the wheels and the vehicle as a whole, and to guarantee safety.

Before securing the nuts on the wheels, graphite lubricant is applied, which allows the fasteners to seat more tightly against the structure during installation, preventing them from “seizing.”
